Lost all my friends

I'm 42, and I've got no friends left.

I was suicidal before, and had such a terrible mood and outlook on life, and I pushed everyone away. I wanted to be alone, to hide under the covers, and to avoid life.

Now I've still got my MDD, but I have it under control, with diet, exercise, and meds.

I have a nice new home, and a great vehicle and a new job. Everything is starting to get better.

But I have nobody to share my joy with. How do I make friends at this age? People are already setup in their patterns and routines of life at this point, and not many my age go about starting new friendships, or relationships. I want friends and I want a woman, and I have neither, and it's making me slip back into a negative mood, despite my other successes.

Thoughts? Advice? Help, please, I need ideas.
