I so agree about getting off of dating apps. Unless you are a person who comes across well by superficial metrics, trying to really showcase who you are in a place that prioritizes superficial things is a bad idea. Men make up about 70-90% of people on dating apps, so the supply and demand aspect is skewed towards those who "read" best in that sort of venue, but if you look at the mall, or a concert, or a baseball game, you'll see all sorts of couples of all shapes, sizes, and economic backgrounds paired up.

Work on dealing with your insecurities and limiting beliefs, work on your people skills and your look, and own what you have to offer in a relationship beyond "I'm nice" and I really think things will go better for you.
