I miss my old self ....

I miss my old self...
Why?
Because once I do not like this now
First,, I can easily get good grades
But now?
It was hard for me
Why?
Maybe because too much memory in my brain that is not important
And I wish I could delete that
And only leave the important memory

Not only that
Now, I feel difficult to get along with friends
Why?
Maybe I haven’t more confident
And I wish I could fix it ...

I miss my old self
Anyone can help me solve this problem ???
