Thanks for the information.
It doesn't not sound like you are having a response to your medication. Your medication side effects should be reduced or completely eliminated by now. And any side effects you did have would be getting better, not worse.
It sounds like you may have anxiety. It could be in response to the stress you have been under since you were diagnosed. To hear you have Parkinson's would be enormously stressful and anxiety provoking. But if you have had a history of these symptoms, it could also be an anxiety disorder.
Either way, talking to someone would help you. Handling such a stressful situation as a serious illness is hard for anyone. Support and self help can go a long way to reducing your anxiety and helping you cope. You can talk to your pastor if you attend church. They are often very helpful and are experienced with counseling. You can also search on line at http://therapists.psychologytoday.com/rms/. A therapist can do a full evaluation and find out exactly what you have and tell you what they can do to help.
Anxiety is very easy to cure. Since it is so common as well, there are numerous resources to help you feel better.
Here are resources that can help:
When You Are Diagnosed With a Life-Threatening Illness (Difficult Times Series) by Jan Jovaag Ansorge
The First Year---Parkinson's Disease: An Essential Guide for the Newly Diagnosed by Jackie Hunt Christensen and Paul Tuite
Heal Your Anxiety Workbook: New Technique for Moving from Panic to Inner Peace by John B. Arden
http://www.parkinson.org/- for support groups
You can find the books on Amazon.com or your local library may have them for you.
Let me know if I can help any further,
