First off, feel you man. Must be rough.

About meeting new people, you could look into trips in the future with groups, a friend of mine met at least one person he keeps in touch with.

Few examples: hiking, climbing, crafts In those places you’re bound to meet people and if you’re at least half decent, you’ll engage with the people there and those might just be your future friends
