I wouldn't worry about it, UKstudent. There are lots of other folks and opportunities out there. And now may not be the best time to be getting romantically involved...take the time to focus on yourself and your recovery.
Are you in Manchester, btw? I went to uni there 20 years ago. But I dropped out due to my drinking & drugging.
And have you checked out any AA meetings? They're not for everyone, but for a lot of us, the AA programme really works...feel free to PM me if you want...I wasn't much older than you probably are when I got sober....and 17 years later, I'm still sober, with no relapses.
