Corri, sounds like you have made some major lifestyle changes recently and that can put even the most emotionally stable person over the edge. Give it some time...at least a couple of weeks and then if the lethargy and lack of motivation doesn't lift get some treatment.
There is a website called 4therapy.com that has a self assessment test you can take. It might help put your mind to rest about the feelings you are having...or lack of feelings I could say.
Another thing, you have made some excellent new friends here on the board. People with open hearts and pure spirits who need comforting and help. As wonderful as it is, the subject matter a very depressing at times. You give out such astute advice but be careful to not get too caught up in the problems of other people. It's great to come and get advice and offer help to others but it can have a negative cost. If are a very emotionally responsible person. You seem to want to help....beyond help actually, you seem to become genuinely a part of finding solutions for others. It gives a sense of being needed and that is wonderful. Just remember to stay objective about it.
Hopefully you will soon have rainbows overhead instead of dark clouds. Feel better Cathy~
