Stress crash??

So I've been dealing with a lot of stress from my fiance and my 3 kids dealing with them by myself with little to no help. I have stressed based seizures. And I have a lot of symptoms that indicate a stress crash like the headaches. The feeling ill off and on. Stomach issues. I can't eat because I'm stressed. It makes me sick to my stomach to eat. I had a stress dream last night where I was yelling in my sleep that woke me and my husband up last night. Idk what to do about it as I travel with my fiance for work. And my doctor is over 15 hours away. Has anyone ever experienced a stress crash and has these symptoms. I'm not pregnant like i thought I was and found out its the stress making me sick.
