That's a pretty good advice, I would suggest OP should take it. I have exact same problem and after doing a lot of thinking alone, (yes off time in nature somewhere peaceful helps), I figured most important thing to do is to latch on to the positive side of the things, you have to fight with yourself to think positive, It could be scary but you have to do it and believe, world is a pretty good place. And as PanJaro said, you are among 5%. What you really need is someone in your life who can tell you everyday that you are fine, there is nothing wrong with you and, what you are doing is perfectly good in terms of amount and size, there is no more requirement to do any more, just keep on truckin. What you have is already pretty Good.

One more thing that is exceptionally important is to stay away from a lot of click-bait stuff, this will always leave you sad or feeling you lack something, and negative people. Basically anything that can amplify feedback loop of negativity that you are already struggling with.

And another most important thing is. Give your mind time to sort itself out. Don't force it to think anything, just let it go a little bit. Your mind has noticed that something in your life is not right, and it is trying to figure it out, like a puzzle, that is why it is trying to take you into a cave and curl up, so it can focus all it processing power on that one thing that it is trying to straighten out and squeze the answers and conclusions for future use.
