Expressing my view of teenagers

(1) You're talking about all teenagers, so the plural is expected.
(2) Some may argue that title capitalisation ought to be observed: "Expressing My View of Teenagers", but I personally think it's fine here, though I can't really explain why. In this respect, when to capitalise a title might be a little ambiguous.

The sSociety has always vilified teenagers as troublesome, defiant and disruptive youths who would revolt against conventional customs and societal norms.

(1) Unless you're referring to a specific society in particular, just "society" is understood to be referring to society in general, and sounds more natural.
(2) "Vilified" might be a little too extreme, bordering on abusive or disparaging slander. Alternatively, you can consider more neutral words, like "depicted", "portrayed" or "painted".

However, are these conceptions of teenagers reasonable to determine em (as) true?

Couldn’'t they have been misunderstood all along?

Alternatively: "Could they have been misunderstood all along?" "Couldn't" and "could" differ very subtly; in my experience, "couldn't" presents an alternative and emphasies that fact, while "could" just brings up a possibility.

This often results in emotional instability, mental disorder and thrill-seeking behaviors, which lead to exhibiting unpredictable and unruly actions.

(1) "Thrill-seeking behaviors" isn't wrong, but the uncountable is far more common and therefore sounds more natural to me.
(2) In my experience, "exhibit" isn't typically used with actions, but rather with qualities or types of behavior. If you insist on using "exhibit", you can write: "which lead to youths exhibiting unpredictability and unruliness." By the way, you need to clarify the subject in front of "exhibiting".

LikeJust as a flower grows best in good soil, the environment they are raised in and the external stimuli also lead them to act in a certain way—sometimes insubordinate and other times, pessimistic and impetuous.

Generally, "like" is used when comparing to a noun: "just like a flower growing in good soil", while "as" is used when comparing with an action or a state: "just as a flower grows best in good soil" (action); "just as the flower is red" (state), etc. Colloquially, however, "like" seems to be used for both anyway.

In truth, we are just like lost souls searching for the right identity and track in life; we often commit mistakes, make reckless decisions, and lack motivation for life.

Alternatively: "searching for the right identity and direction in life". "Direction" is commonly used with "life".

We may appear hardtough on the outside, but our hearts are as fragile as delicate flower petals.

"Hard" isn't really used when referring to people. You can use "tough" or "thick-skinned".

You were once teenagers too; don’t you recognize yourselves in our faceus?

"In our faces" might suggest you're talking only about physical appearances, while "in us" implies something deeper, such as one's personality or character.

Treat us with kindness and understanding; you will be surprised to see how willingly we reflectciprocate that same kindness back.

Titles have important words capitalised.

The sSociety has always vilified teenagers as troublesome, defiant and disruptive youths who would revolt against conventional customs and societal norms.

No definite article before society.

You might have heard adults saying, “Hhow problematic teenagers are nowadays,” stereotyping the young people by pointing out the wrongdoings of thea minority.

However, are these conceptionviews of teenagers reasonable to determine as true?

As a teenager myself, I do acknowledge that we can sometimes be rebellious and tend to misbehave toand challenge the status quo.

However, at the same time, we are also misconceiveunderstood because society fails to understand our struggles and ways of approaching life.

Simply put, teenage years, or adolescence, are a major phase in human life where we experience a range of internal and external changes—: mentally, physically and emotionally as well.

This often results in emotional instability, mental disorders and thrill-seeking behaviors, which leads to teenagers exhibiting unpredictable and unruly actions.

Like a flower grows best in good soil, the environment they are raised in and the external stimuli alsothe experience lead them to act in a certain way—: sometimes insubordinate and other times, pessimistic and impetuous.

Ultimately, as thea last request to those who misjudge us, do not define us by the negative label society imposes.

"Exhibiting actions" sounds a bit weird.

Furthermore, theiour surroundings also profoundly influence theiour character.

The point of view should stay consistent throughout the text. You earlier said "...where we experience..." so you should stick to this perspective.

LikeJust as a flower grows best in good soil, the environment theywe are raised in and the external stimuli we receive also lead themus to act in a certain way—sometimes insubordinately and other times, pessimistically and impetuously.

Since you're describing how you act, you should use adverbs rather than adjectives.

In truth, we are just like lost souls searching for the right identity and track in life; we often commitmake mistakes, make and reckless decisions, and lack motivation forin life.

"Commit mistakes" is not wrong but sounds quite formal.

People should understand that we need proper guidance, support and encouragement because, in this transitional period, our consciousness couldan easily be dominated by depravity, and we couldcausing us to deviate from the right path in life.

Ultimately, as thea last request to those who misjudge us, do not define us by the negative labels society imposes on us.

You were once teenagers too; - don’t you recognize yourselves in our faces?

I think a dash seems more natural than a semicolon here. Using a dash here also avoids overusing semicolons, which is something to consider since there's one in the next sentence.
