Need for a vent

I am have probably found out why i dont have many friends anymore.

I only have about 2 friends and i think one does have someone better to hang out with and it kinda hurts a bit because we used to be in a relationship but we broke up and now are good friends. at least she said smth like that. but now she bearly send a messages to me or talk. i think the only reason we are now friends is that we are in the same school. And the other friend has been a good friend for already 10 years but now they are in a different school and i have only played video games with him. I would like to hang out outside of videogames but he has such a busy schedule so it feels like i cant or smth.

but anyways the reason might be because i am just bad at socializing and i have troubles to just to send messages to my friends and family because i think i might be a nuisance and it always feels like im disturbing them. and also i just might be just too annoying or boring to hang out with. i don't know how to improve myself or i might but im too bad or scared to try to talk to people. but yeah. feels good to tell somewhere about things

(sry for bad english. im from finland so yeah)
