Hi Lacee,
What Ann said is really good. One other thing that happened to me was that when something started surfacing from my past I without knowing it started working very hard to keep it stuffed down. It used all of my energy. I finally got so so tired that I had to let go and let it come up and face it.
Another thing that affected me this way was menopause. It zapped a lot of my energy. I still haven't regained the energy I lost about 4 years ago. I started feeling blue about the same time.
Talking about it always helps so keep posting.
Hugs,
MG
