I sooo relate. I hate it when my mind gets all fuzzy and I can't think straight. I'm so sorry you feel like that now. I'm glad to hear you have a psychiatrist treating you. Are you talking to someone regularly? Lots of people here say that it's really a good thing to do.
I know it's disheartening to fall down from a good place. It takes so much energy to get back up.
You are very brave and you are fighting the best you can.
I hope you feel the support you need here. Most of us have experienced what you are feeling and understand.
I hope you feel better soon.
