End of my Rope

I'm at the end of my rope. My life is just about trying to make it through the day with pain and fatigue. I don't even know what I'm doing on this planet. I'm still gireving the person I used to be and the the life I could have had. I 'm constantly on edge and don't think anything will get better. What do you do when you have been in flare after flare and have a few autoimmune diseases you are trying to manage? Quality of life sucks. Not many people have been understanding and I'm in the middle of a divorce with a psychopath who was not only abusive, but actively incited flares while telling me my autoiimune diseases are my fault, shamed me for taking medication, and was delulu enough to keep saying that there are natural cures to these disease. Not to mention, all the while he made fun of my health and flares, and shamed me for being a burden. How does anyone who has autoimmune disorders handle chronic trauma ? I would love to hear how people bounced back from a mental low like this. Any encouragement would help. Please no unkind or mean comments.
