Sorry you are having such an awful time.
Crap stuff does happen to good people.
Bad luck happens to us all. It really is about working through it with a postive mental attitude and resourcing the help you need. Think this way - "You win some, you lose some". It happens to all of us... Embrace this fact - then you can sort out how you are going to plan and attack your problems.
You can do it!
Don't let feeling sorry for yourself overwhelm you!
Yes, things are horrible right now! But, yes you will have more problems in the future. We all do! Life is about HOW GOOD YOU ARE AT SOLVING PROBLEMS. You cannot undo what has happened.
I think I can safely say, everyone I know can think of something they wished never happened. We all want to undo getting certain diseases! If only! But you don't have a time machine and you can only deal with the here and now and the tomorrow.
Don't let this current speight of bad luck overwhelm you.... I dare say, getting more and more upset is just going to bring on more flare ups! Instead, consolidate your resources including your will power, your resilience, supports and friends, and get busy trying to tackle your health issue and employment.
Check out the many forums here that can assist you. There are so many things you can do for your health problem including all the cleanses, parasite, bowel and supplementation.
Good luck and hugs.
