As far as i can tell from your pictures, you have flukes (the orange blob and the small whitish curved one looks just like schistosoma or the other name is bilharzia) and roundworms quite possible. The skin symptoms could be them migrating and/or your body's reaction to toxins.
You have no other choice but not to give up, for your kids. When you have round and flatworms together, they can both disseminate and your immune system cannot keep up anymore. You need meds to kill them and herbs and minerals to support your body. It costs time and money but it is possible. I am also a mum of only one but i feel it is hard enough already.
Don't go back to the doctors. They dont know how to treat. They will never diagnose you. Your hair will grow back and you will feel better but it is hard work to get rid of these things once they make you so ill. It is not impossible though. Contact mattk3 and sharkman on this forum. They are both incredibly knowledgeable and helpful. They both cured themselves of a bad infection.
I will send you a pm.
