I will have the same kind of episode of which you speak. My bad times will always show up in the morning. Today was one of those days but I took the step and reached out for help as I knew if I did not, I would just feel bad all day. You have done the same
I am wondering if perhaps your Mother needing less care is making you feel less needed?
I too get nervous going to the therapist as I don't know how to explain my feelings sometimes. I did see my P-doc yesterday and she felt I was fine.............and stay on current meds.
Feeling bad physically may be kicking in your depression. I am a very poor patient. Can you pamper yourself for a few days?
If you need to see you physician for a med switch you will be able to deal with that. I know you have before. You have my support.
Many hugs for you.
