Hi, and welcome to the forum.

Sorry you are having problems and are anxious about your condition.

You say have had an MRI that will have ruled out some possibilities - it was ordered by your gp, who also previously mentioned parkinson's, due to some of the things you have experienced and concern you. I would look to seeing a movement disorder specialist to either rule out or confirm parkinsons, they are the people with the specialist knowledge and experience with PD.

Neither your GP nor a general neurologist will have this expertise, though they will have enough understanding to know that it MAY be a possibility.

Diagnosis of PD is a process of elimination, as well as observation. You say you have a lot of stress and are anxious, along with depression. It is true that PD can worsen with stress, and become more noticeable, that in itself doesn't mean you have it, or that you don't. You seem to have some conviction that you have a physical condition on top of the depression, so go with your gut feeling on this and ask for a referral and get yourself checked out by the right people, and one way or another you should start to get some answers.

I wish you all the best in finding the answers you need. In the meantime whether your symptoms are a result of depression or something else it would help to be as active as you can be, there is a lot of research to say that exercise is a mood enhancer, and even small amounts of activity can be of benefit helping across the board mentally, physically, and emotionally.

Take care
Lindy
