Thank you, @colleenyoung. I read the article you suggested and will keep the suggested medications in mind. After the steroid shot and steroid pill pack, my hives did subside. However, I have had a new breakout although this time isn't as bad yet. I am hoping that there might be some residual effect from all of the steroid doses I had on the last bout. I still believe that the hives are stress induced.

Things are not necessarily better with my husband's health. He continues to hallucinate, be delusional, and irrational. Though I know that these challenges are because of his diseases, it is still difficult to deal with him all day, every day. My patience runs thin; my responsibilities and work load remain high. He won't let our caregiver assist him on many things -- he only allows me to help him. He is a tough one to handle sometimes.

I am receiving counseling through a Hospice program called Supportive Care for Dementia. I am being encouraged to visit care facilities and think about placing my husband in a place where he can benefit from 24 hour care. My last doctor suggested that my body may be telling me (with the hives) that I can't go much further. This is very stressful in itself. It isn't just the cost of care in a facility, which will be all out of pocket for us, but also the fact that he hasn't forgotten people -- especially me. I am not sure that I can look into those blue eyes I fell in love with years ago, as I leave him in a place where he doesn't want to be. My children are fearful that they are going to lose me, along with their stepfather. Each of these things are stressful; added together they are overwhelming.
Thank you for your support and for the helpful comments.

Thank you @colleenacarney . At this point in time, my hives have subsided. It took a steroid shot, plus a round of steroid drugs to get them under control. Presently, I have hired in-home care to help with my husband, and to allow me a chance to run to the store for meds and groceries, as well as an occasional walk. Unfortunately, the agency tends to send a different caregiver each day, which causes more confusion for my husband, and work for me. He became so agitated after the third day in a row of a different person each time, that it took me 2 hours to get him calmed. I don't think it is worth the expense -- emotionally or monetarily. Yes, I spoke with the agency about the need to be consistent in who they send; however, we all know how difficult it is for employers to find and keep good employees these days.

I am not sure what to avoid... but if I get even 10 minutes to exercise, or journal, it seems to help.
