People my age are supposed to hang out with friends after school, participate in school activities, and all that jazz.
I just can't.

I have trouble making new friends because I'm often so concerned with what they'll think of me, and I'm always worried about what I should say, what I should do. I know people don't care that much, but my mind just tells me they do. I can't hold a conversation either. Someone comes up to me and goes "hey whats up", the only thing I can reply with is "hi -waves-" and then theres like a long draft of awkward silence before they go "okay bye". It makes me face/palm. I just don't know what to talk about to create a nice conversation.
And worse, I have no personality or wit. Like srsly, I'm not funny and I'm probably the most boring person you'll meet. My friends can think of replies really quickly and make everybody laugh while I'm just like...

how do they do that? I rarely hang out on weekends(I'm so lame the point where my "friends" dont invite me to anything anymore.) , and tbh, I've never taken a photo with friends before. (except maybe 5 years ago u_u)
The weird part is that I'm completely fine when I'm not at school.

I say whatever I want, and I actually have a personality. I just don't know what stops me at school x_x
Its just so...sad. Like it makes me genuinely sad that I have to waste my school life being this way. Can anybody give me advice, especially those that have gone through the same thing as me? Being social is just such a challenge. ):
