I know how it feels, although I have never sought help for it. My husband and I both lost our jobs at the same time and had to make drastic decisions to save ourselves from financial ruin. We had to sell our home which was so difficult for me and I had to do it alone while husband was in training for another job. My daughter hired me to watch the children to help some money coming in for us, but then she lost her job! I cried and cried, not being able to stop and the whole world seemed to come crashing down around me. I felt so helpless, so vulnerable and I had urges to pull the covers over my head and hide.
Melt downs happen whether there is something that sparks it or nothing at all in particular. It was the right thing to do to go and get help for it.
I also though that dieting would help me, but there is a catch 22 with dieting and having trouble coping. I did something that really helped me, I ate just a bit less by using a bowl that held 2 cups. I allowed anything I wanted in the bowl, but I only ate 3-4 bowls of food a day. This was just to start something, anything, to help myself prepare to diet again. I soon discovered that I felt better eating "just enough" and within a few months I was ready to feel even better. Each person is different, so this is something that worked for me. It's my way to a gentle and nurturing start when life seems overwhelming.
