I feel like I'm going insane

Long story short. There is this person which I used to be very good friends with. After I had to move to another city for university reasons we grew distant big time and ever since then I've never been able to reconnect with them.

It really fucking sucks because of all the good memories... I wanna hang out with them again someday but I'm too fucking scared to try and even ask... I feel like they don't even wanna talk with me anymore ;_;

Or is this just a part of growing up? I know my father has zero contact to his childhood friends but then again my mother and sister has still very good connection with their friends... Maybe it's just a "man" thing?

I-I don't know man... I just feel so lost and confused over what to do and what to feel...
