Hi Jane, welcome here,
I hear you. There is a lot of people that dont discuss their "multiple" disabilities so we the community often dont have a real grip on the extent of that. Hence when it happens to us we think "why me" based on that.
I'm 63yo, at 24yo in 1979, my older brother suicided and from then on my life seemed unique to me- a story of being worse off. My uncle went the same way so this endorsed my view. Then in the next two decades- back injury, marriage break up with kids, my own suicide attempt and my sisters, my father my only real rock passed on and then the challenges of being diagnosed with bipolar and dysthymia. Recently I've had deep vein thrombosis and arthritis in both knees.
However, I also recently built my second caravan, prior to that built my own house - alone! How? and how did I overcome these odds mentally?
Well the secret isnt such a secret, it is discovering positive thinking and that changed my life remarkably. It turned out I was indeed a negative thinker (as were my family members). I attended one motivational speech (see the thread below) and in 30 minutes my life changed.
For example- when I first had my back injury I needed to take medicine daily, then as the other issues came along more tablets became daunting until I realised- if I'm taking one tablet, what is the real difference in taking 5 or 10 more?
There are other ways to look at these challenges, but it is far better to ask you to read the first post of the following threads I've written on the topic.

I hope you get some benefit from those above. As you'd be aware managing your life with your illnesses to achieve the maximum of what you can is the aim.
