I'm finding that along with having Parkinson's, which is more than enough to cope with, I'm also having problems avoiding falling into vicious cycles which have a psychological component, like the following:
1) Anxiety and fear causing me to sleep poorly and/or take too much anti-anxiety medication, resulting in extreme weakness and fatigue which sometimes makes me feel like I'm dying, causing anxiety and fear.
2) Sadness over deaths of parents over the last few years and resulting feeling of being lost in the world, with an identity largely based on my relationship to my parents also lost, resulting in anxiety and fear (see #1) which weakens my capacity to come to terms with grief.
3) Loneliness due to lack of friends or significant other, resulting from my reluctance to socialize and have people see my arm trembling like a leaf, increasing my depression and anxiety.
4) Extreme weakness and fatigue making it difficult for me to exercise as much as I should, thereby sapping my strength and morale and leading to more anxiety, fear,
weakness, and fatigue.
5) Dependence upon too many doctors/specialists prescribing too many pills with no notion of how all of the pills that I have to take interact as a group, causing me to feel generally bad a lot of the time, leading me to see new specialists prescribing more pills.
