Anyone raising two kids on there own with Severe AF

Hi, I have been dealing with AF for 2 years but didn't know it. Had a bad reaction to Anti-Depressants and Benzo that sent me there. I was doing ok for about the last 6 months or so but have sense crashed again and now have been diagnosed with severe adrenal fatigue. Stage 5 by 24 hour cortisol test. Or 3C. Anyways I am at the end of my rope sort of speak and so is my husband I think. I am raising two small children while my husband works out of town and am so sick all the time. Mentally can't handle it, yelling at them, barely being able to deal with day to day life. I have had to pull my son out of some of his programs and feel so defeated. Just wondering if anyone else is dealing with this kind of situation and if they have any words of encouragement. I truly feel that everyone would be better off if I was not here.
