I really do feel for you, but I don't really know how I can help you, except that maybe I can pass on some advice that I have come to live by.
A couple of years ago, I started looking after my father in law. When I made the decision to do this, my biggest concern was the loss of my freedom that would result from being the only person that looked after him.
I didn't realise how much it would effect me, until I got up one morning & I was stood in the kitchen making his breakfast, after cleaning him & the bathroom up.
I was looking out of the window at the rain, when a voice in my head seemed to say, what's the point, is there any reason to try & go on any longer?
What do I have to look forward to?
I can't afford any respite care, I can't go anywhere for more than a few hours, I can't use the van I'm converting, I'm always tired.
But then something I was told years ago by my mum came into my mind, she said that if you want to be happy, then try to look for the beauty that is right there, in front of your eyes, when you look at something, really look. look at a leaf, the way it grows, the colour, the texture, the way it's attached to the branch.
When you remember someone, then remember all the good times you had with them, all the little things that made you happy!
So I do, it's amazing how much beauty you can see in people, animals, birds, insects, grass, trees & flowers etc.,
I took up photography, I try to convey the way an image makes me feel, it's good to have something to take my mind off of the cage I now find myself in.
There's always hope, there's always light at the end of the tunnel.
All the very best to you, Phill
