Hi Fishcake,
It's a real shame to hear that your fish-keeping experience has brought you so much anxiety and stress, especially with your health being not as good as you'd like it to be.
I think that whatever you decide to do, you shouldn't beat yourself up too much about things that have gone wrong. I'm sure that there are thousands of people who buy pets of all sorts without having the slightest intention of ever trying to keep them happy and well, and you definately don't fall into that category!!
I wish I could take your fish myself, but I'm right up in the northeast of Scotland, so that would be impossible. Two suggestions spring to mind about rehoming your fish, if that's what you definately decide to do:
1. Find if you have a local aquarist society – get the main contact's details and ask him/her for help re: rehoming (or, if they were happy to do so, and you felt you wanted to try, helping you get over your tank/fish issues). They may be able to put the word out to knowledgeable people who could step in.
2. Try Gumtree, that way you could ask the relevant questions about experience if anyone responds to your ad.
If your fish and tanks are making you miserable, then giving up for now and trying again, perhaps, at a later date
is not such a bad (or permanent) option. No doubt when you come back to the hobby we'll all still be here moaning, fretting and talking about poo!
