Hey crisscross, I am introverted male myself. Things I've considered have required inward thinking.

-What do I like to do? (i.e. playing music, drawing, trading card games, hiking / outdoor sports, playing competitive sports, playing video games)
-How do I use these things to my advantage to meet new people and potentially a new relationship?

Do the things you love without the core drive to be dating someone. You'll find that focusing on the things you like while keeping dating as a lesser goal, will get you to the point of dating someone.

I have depression and anxiety myself, so I hate it when people tell me to just be confident. You do need a little bit of confidence, just a little. It doesn't necessarily need to be you, but the things you do and keep you busy. Whether it would be confidence in the work you do or the hobbies and activities you engage in. Have confidence in the things you do.

I have faith in your aim to date. You just found a good job thats going well. That's most of the battle.
