I'm the same, but unlike you I'm at college just now and have been for a year and a half. Before that I was working 3 jobs, before that a full time job and before that I was at college studying something else...
And yet I have 3 close friends ( which I still don't see, just speak to every few days ) .. I've met plenty of people through jobs that I would consider friends then I leave or they leave work and we never really speak again or ever meet up etc!
I find it so hard as I'm quite a shy person to start with but then once I've met someone a few times I'm my normal bubbly chatty self ... I also go to college 2 days a week, work in the salon 2 days a week, work in a pub 3-5 days a week, have a mobile business ( which is on the back burner as I don't have time ) and have a boyfriend ... So I don't have time to meet up with my current friends, and due to this I've actually lost a lot of my school friends as never had the weekends off to go out with them, to the point they stopped asking me on nights out!
So the only people I see are my mum dad and brother, college folk, work mates and once a week I see my boyfriend... I don't have time to be social with friends and yet I am gutted that I don't have many!!
My boyfriend has 3 groups of close friends and they all consist of 6-10 friends in each group! And he gets on well with so many people that he could literally see someone in the street he knows and go to the pub with them, but not me! I'm so jealous and it gets me upset quite a lot that he's basically all I have xx
