Dear Lynn,
Many of the symptoms you are complaining of are suggestive of depression.
When depressed:
You feel sad a lot, and it doesn't go away.
You feel guilty; you think that you're no good; you have no confidence.
Life seems meaningless, and you don't think anything good is ever going to happen again. You feel empty and hopeless.
You lose interest in ordinary pleasures like music, sports, friends, or having fun. You really want to be left alone most of the time.
It's hard to make up you mind. You forget things, and it's hard to concentrate.
You get angry or irritated often. You're so touchy that you lose control for no particular reason. You over-react.
There's often a change in sleeping and eating habits.
You feel restless or tired most of the time.
You think about death a lot or thoughts about suicide pop into your mind.
I recommend you see a psychiatrist, he/she can monitor your symptoms, and adjust your medications appropriately.
As you mentioned you may also benefit from therapy, to help understanding and hopefully work with your feelings.
Best Wishes!
