I am very sad today and. I am alone all the time iam alon aevery day and i liftI miss (?) my friend.

Not 100% certain what "lift" was intended to mean.

I am very sad today and all the time iI am alon avery day and ie, almost every day. I also lieft my friend

I am very sad today, and all the time iI am alon avery day and ie. I lieft my friend.

When a sentence can be split into two standalone sentences, add a comma before and
You already wrote "all the time," so you don't need to add "every day"
I assumed you meant to write "left" instead of "lift"
Added punctuation so it sounds better

I'm very sad today and all the time ia. I'm alon ae every day and i liftI miss my friend.

I wasn't sure what you meant by "I lift my friend" so I guessed.
