How do I stop hating myself?

I have zero self confidence, zero self esteem, grew up with hardly any friends, no social life, and failed at every attempt to improve my life.

I feel like I'm being punished for how my life has turned out so far. People who I thought I could count on for moral support blocking and ghosting me, a car going through my living room two years ago, a friend dying suddenly and getting school funding cut for taking time off to deal with it, having the roof nearly blown off from a storm, my CRA account hacked and blocked, being unable to hold down a full time job due to mental health struggles, and failing at every attempt to improve my life.

People have suggested posting positive affirmations around my bedroom and/or in a mirror. It's one thing to tell myself positive affirmations, but it's a different thing to believe it.

Just like there are people out there who are born lucky, there are people out there who are just born to lose. I look at myself and all I see is a failure and a loser. I'm just tired of losing at life.
