Somatic symptoms are your minds way dealing with emotional overload. It's not very nice when you are unable to control body movements. It can be shameful and embarrassing. No you are not crazy. You do have many issues that are happening.
Please try to be gentle with yourself as much as possible. I have found that writing things down helps it to get out of my head. Are you seeing a good psychiatrist and therapist? Take one day at a time or even five minutes at a time if this is what helps you through.
