lol I suffer the same issue. but my problem is im just too lazy. I have active firends who want to hang out alllllll ALLLL the time and I just keep rejecting them. like i like to hang with them in school ( when i was in highschool) and now that im in my first year of uni I just lost contact with them because its too much of an effort organizing something. so now im sort of a loner because i havnt built any real friendship in uni. (usually ppl tend to stick with their highschool firends in uni) but now i regret it and i miss having thristy firends

I need to go back in touch with them but im too lazy and nervous lol i feel like they will act a bit cold not because their mad but just because we havnt spoken in so long so it will be maybe a bit weird idk? :S they all stuck together im like the guy who chose to dissapear :/
but ya my advice is next time ANY ONE! offers you a time to hang out with them or w/e just do it. because thats how good friendships start. you just have to break the first few weeks/months of awkwardness and then it turns into super ocmfortable real frendships werre you wont need to think too much about hwat your saying or doing ect. you wont dissapoint them trust me
