Ow, I am so sorry you are having such a trouble. Burns are one of the most painful things to deal with. Use a good antibiotic salve to keep the burn from getting infected and if it is large I would keep it wrapped for a couple days at least to keep it clean. Hope you feel better.
As for feeling sorry for myself. I am one of those kooky people who rarely feel sorry for themselves. Whenever something happens bad to me whether it is injury, sickness, financial, family, whatever I usually boohoo for about an hour then pick myself up and always realize someone somewhere has it worse than I do so I then just get on with my life. It has always helped me get through whatever bad is going on to know that whatever is going on with me is minimal compared to someone else I could help in some way.
Hope you get to feeling better real soon.
