Forget Tinder and other social media apps, they don't bring joy or reason to live; you get someone to sleep with, and in the morning, it's the same feeling and cycle. Firget those apps. They are trash. You need to be active in the physical world based on your post.
My advice is relocate or get actively involved in charity works, get in touch with the physical world. That's what you need. I know the pandemic has made life more difficult and less physical, but get your shot (for prevention) and get active.
Remain strong, you'll overcome this phase.
