Mouka, if you think that ending your life will be less devastating for your family than having a PD diagnosis then you really do need counseling!.
As our guidelines request that members please keep discussion of suicide to our special forum for that I have had to edit your post. Here is the link to our SOS forum
http://neurotalk.psychcentral.com/forum29.html
We have this guideline as it can be very triggering and upsetting for others to read suicidal posts on our other health forums.
I really do think our members have tried to be as helpful to you as they possibly can be. You have had a physician tell you that you do not have PD and our members have mentioned many other issues that could cause the symptoms that are troubling you.
Once you are back home, you can follow up with other physicians who will hopefully confirm what you have already been told, that you do not have PD.
