Hi Kym,
Did you read the replies? Noone thinks badly of you. I know it is hard not to worry, but reread them and look at the support you have here. Everyone is behind you 100%. Not one person has said this is your fault, that you did anything to deserve this, or that you shouldn't be allowed to live your life. This is your perception, and it is inaccurate.
The question is not what people think, but what can be done to make you feel better? Do you see a counsellor? I think that would be a very good start if not. It will be hard, I'm not going to lie, but it needs to get to the root to start making you feel better, or else you can never heal. How about emailing the Samaritans? They have been helpful to me in the past, and it's a confidential service? I know I'm not much, but you can also contact me if you wish to contact someone who is understanding through personal reasons.
You take care,
