Well done on the drinking front , I know how hard it is , but it does become easier. Try not to be so hard on yourself, I think you are doing really well . You are going through a really stressful time and I think if you step back and look at how well you are doing you will be pleased .
There are Meetup groups that arrange cinema get togethers etc . Is there anything that you always wanted to do but couldn’t because you had the kids and married etc. ? I did something very few people have done and it’s great for the self esteem and it’s a great talking point ( kinda makes me look interesting )
