The gaming groups near me are always full of people your age. I mean gaming as in the table top stuff. Dunno if that'll be your bag. I know two dudes that regularly attend Andy's Man's Club. They're both mid thirties. But they just get together and play pool and stuff. They usually gather down the pub. The group was formed to combat men's mental health. I always hear good things about them. Hey. You could always volunteer too. The food banks always need people. Would you consider fostering animals? The cat rescue people up my way are always looking for people. I think it's apparent from your post that you're lonely.
