Towards the end of my drinking, I was isolating myself from my family. I did have to give up all the friends (as they were drinking buddies) and I split from my boyfriend after 6 years. I am now moving in with my parents (long story but it had to do with my parents trying to evict my ex-boyfriend from the house that we rented from them). I work, go to group meetings everyday during the week, AA meetings on the weekend and will start seeing my sponsor on a regular basis. I feel that I had to let go of everyone in my life and completely start over from scratch. I started with group/meetings and am now finding my family again. Eventually, I will branch out to make new (sober) friends and will find someone special. Take baby steps... it all doesn't have to happen at once.
Once I said good bye to all my friends and my boyfriend, I didn't think that I would ever find people to be around. But once you start, slowly, putting yourself out there, things will just happen.
