Feeling like a failure in life

Thats good you get those spurts. Do things in the times that you don't and you will probably find it helps you and you get more.

Felt that my entire life, it's hard, but you can't just compare your life to others it's not fair to yourself (it's a lot easier said than done) just focus on what makes you happy and everything will come in time.

Definitely not alone. I was married but am now divorced. Had a house but lost it in the divorce. Without my partner, I have none of that because I am unable to work because of my medical and mental illness so I see all of my friends with their houses and spouses and now they’re even starting to have babies (which I want more than anything in the world) and I feel like I will never have any of that again. I’m just stuck here with nothing.
