bigblackdog, I understand, too. Please call your doc and tell him/her how you feel. It sounds like your meds need to be changed.
Do you have any family members or friends who can help you out?
I might have asked this question before, but are you seeing a therapist? Therapists can be very helpful in supporting us to keep on keeping on.
I have decided that life is a battle. We get one skirmish dealt with and another comes along. And sometimes we just battle and battle and battle, seemingly without end. All we can do is to take one day at a time.
Please do hang in here. And, as pegasus said, be nice to yourself. What are some things in the past that you have enjoyed doing that aren't big draining things?
