Welcome to the forum. As somebody who has posted on here in times of need - I know personally how just knowing that there are people to talk to out there really helps.
I have been in your situation and am now 5 years down the line. I read in woman and home a couple of years ago that things go in cycles/phases during a breakup. First the loss and trying to find out what went wrong, then the "lets start doing everything Ive always wanted to do", then eventually you settle down to a new normality. I certainly felt all of these things.
It wasn't easy to start off with but I joined a local theatre group - I don't want to be on stage, but have found a good social life either just attending the performances (the theatre is one place you can go along and nobody looks at you weird), working front of house, back stage or even doing bar duty. Whilst I am doing this I can be me and for a short time everything else takes a back burner.
I really hope that your friends and family will support you at this time, but if not there are a whole new bunch of friends waiting for you here. Feel free to PM me if you want to chat.
