Sometimes it does seem like the only way to work things out is to give up and leave, but things always have a way of resolving themselves and happening as they should.
Our eyesight problems can seriously depress us when things go so badly wrong, and with all the things you have had to work through recently this has sadly happened with you.
I am hoping that you are getting the help and support you need because there are always those around who will want to be there for us when things get bad. I'm sure that most of us here can relate to having a very bad time with KC but sadly you have had to deal with a lot recently and this can all take over and turn your life upside down.
Those without KC may not be able to understand why you are in the place you are now in, but the only real truth to take from this is that you did what felt right to you at the time and now you just need to move on. We can only take so much and struggle to cope before things fall apart and the only way we might see is to give up. But you are going to change things as it must have taken a lot to come here and post what you have. Saying that you are in a bad place will let those who care about you know and allow them to support you.
Please take some time out for you and know that we are thinking of you and wishing you all the best. Take care, love and (((safe hugs))) Sweet X x X
