Throwing blame back on other people for not understanding your hardships is self-serving and a fundamentally dismissive attitude. Mental issues do not absolve actions. You feel that you are not fully responsible for your actions and that is actually fine - but as a person who caused harm you should own your ACTIONS, full stop.
"I fucked up. I had a mental break and caused hurt to others.I am sorry for those actions and I am working to better handle my mental issues."
Since they ask at the end what people want, it is simply that. Accept that you are the person that did these acts and hurt others. Forgive yourself for doing it, (internally) but don't deny responsibility.
If it helps, blame your Public Self for being an asshole while your True Self can empathize with those hurt by Public Self. Right now you can't empathize because you are so concerned about deflecting blame from yourself. But blame is shitty and doesn't help anything - ignore blame and accept responsibility for your actions.
Things can't improve until you do that first.
