Firstly, the problem with oversharing on the internet. Is no matter how anonymous you *want* to stay. You probably *could* be found based on the info you give. So fair (albeit obvious) warning there.

And there's only ever really two (positive) ways these things can go. 1. Letting you know that you're not alone & that other people are going through similar things to you. Then maybe it would help you to find those people and share your stories. (Go to therapy.) Or 2. Understanding perspective. (Finding solutions to said problems.)

Sounds like you have a stable job / income.

You have a family around you to take care of. And ones who allow you to stay under their roof.

You've had relationships before. (Even bad experiences give you experience at least. You even seem to understand your own personal flaws that might've effected them. So as long as you learn from it...)

You went to/afforded college. 

About 18% percent of the US has been diagnosed with depression. So about 62 million people. (Though that varies and might not really be accurate.) 

I'd strongly consider not distancing yourself from family or friends solely on their political and religious beliefs. (Unless it's specifically alienating you/forcing you to participate.) Because there's a lot more to life than that.

And not to give cheesy advice. But if you don't feel like there's any *one* or *specific* thing(s) that would suddenly make life better (if changed). I'd start going to the gym and working out. And if you can't afford that, going for daily walks outside. (That, and decompressing by turning off social media & your phone for a period of time. (Hours/Days) If you're particularly addicted to that.) Some sun and some exercise can do the body and mind some good.
