Sorry you are feeling overwhelmed now, have you tried seeking help from a therapist? You don't suck, be kind on yourself, because degrading yourself won't make you life turn around. Depending on what kind of bad deisions you are making, you may be able avoid them: every kind of bad decisions, write them in a journal, how did it come to that, what lesson you leaned from it, several scenario to avoid them. You may realise that some of those are out of your control = not your fault. Check your general environment, do you think you suk because you are in an abusive/toxic environment? Look for your country's mental health helpline if you have one. I'm afraid ranting on FML won't help you much.

Well, the typing Tourette syndrome may be a factor in why you can’t get what you feel like you deserve

Say "fuck" again. That'll turn back time. Seriously, though, this is self destructive behaviour and won't make anything better. Seek therapy to help you be kinder to yourself.

Things are looking up for you! You just set a Guinness World Record for "The Most Uses of Fuck on Fuck My Life" Surely, that comes with some prize money, commercial endorsement opportunities and invites to talk shows. Never mind the prestige!

Seek therapy my friend, it does wonders.

I empathize deeply with you and I'm so sorry you're struggling 💜 please seek out therapy or counseling, it's ok to ask for help 💜
