It sounds like your family loves you. I wish somebody would throw me a party because they noticed that I was feeling down.
I'm no shrink, but it looks to me like you have to work on your own sense of self-worth and stop comparing yourself to others. In my own life I've found that to be a slippery slope. There's always someone richer, better looking, more talented -- whatever. If you spend a lot of time on "social" media, you can easily fall into that trap of comparing yourself ot others. Just do you. Unplug for a couple days and get some exercise, do some thinking and meditating.
Good luck.
