If it helps, this happens to older adults too. I did much the same thing following a rather great tragedy. I became depressed, isolated, pushed people away at the exact moment I needed them most. Now with some distance, I see and understand what happened and I feel horrible about it.

So, I set up my plan. I got on MEETUP.COM and found some meetup dinners and activities. I have new acquaintances, not friends yet, but some acquaintances. I like the outdoors so I now volunteer at an outdoor center, more acquaintances. I set a goal to run a half marathon, self improvement at 62. I began a spiritual quest, visiting ashrams, Buddhist Centers and churches, more acquaintances. I set another goal, to meet 100 new people by end of May. The rule of thumb is 10:1, meet 10, find 1 friend. I joined a biking club, more acquaintances. I keep up on my meds and began finding sites, like this with a community.

It stinks at any age to start over. The trick is to do one thing then another and another but, it won’t get any better unless you become an active participant of your solution. Just keep trying and trying, and trying. You can do it if a 62 year old guy can do it.
