Getting really tired of this crap

I am tired. Winter is making all my joints ache, especially my back and hips. I have all this running around to do, and all these things to settle, and I can barely stand the pain sometimes.
I don't have time to arrange for a doctor. They are sucking all my time and energy from me, and I can't seem to raise enough energy to give a crap.
I long for a time in my life when I can take care of just myself because they are all handling their own misery. After all, I have enough of my own misery to worry about.
I would be satisfied with a studio apartment, proided that there was enough of a kitchen and bathing area. Just me, my computer and tv, a small place for a small life, which is the best that I can expect at this point.
But no, I have 2 very high maintenance people to look after, and I'm failing to manage everything. Well, it's not blowing up quite yet, but give it time.
In the meantime, I hope that I can actually make it through this stage of life intact, in some way. I just don't know how.
