You've got to talk to someone, actually posting on here is talking at one level, not as good as face to face but better than nowt. What I'd say about the photo its your reaction to it that's important, it brings out something positive and that's great.
Talk to a friend if you can and the your doctor and then a councellor. Not speaking about stuff resonates with me strongly but you do need to speak to move forward. I'm 50 and in the middle of a divorce, it's quite easy to see the glass as much much less than half full, equally it's possible to see lots of opportunity ahead. You are definitely not alone in how you're feeling, realising that in itself is important.
