My daughter spoke with me about the same type of emotional ups and downs. I told her that I was sure that it was not her, but probably a reaction to the many different medications that she was on. I felt that each medication had its own side-effects which caused changes in the body. Each side effect caused her to react emotionally to the changes - thus - her emotional roller coaster. I do not know that this is a fact, but I wanted her to know that she WAS NOT losing her mind! I also wanted her to know that, regardless of her mood, we supported her, loved her and were here to help her!
It sounds as if your family is doing the same for you and I am so glad. Not everyone with this disease has the benefit of a supportive family. You are raising small children which, in and of itself, can cause a lot of emotional reactions. Add to that your illness, your medications, your pains - You are supposed to react to all of this emotionally! The good thing is the fact that you recognize that your emotions are unpredictable. Be honest about them and yor family will understand.
