You definitely need to read Dr. Clark's book. You don't need to live your life as an invalid like this.
It's an old saw but true. EVERY single thing you talk about can be traced back to parasites. If you want my take on it, I talk about what I've discovered over on my thread in spirituality, under "Haven't they stolen enough already?".
And yes, I do have some unusual information, quite 'crazy' sounding by the standards of the information left us today. But it's painfully true, unfortunately.
Just one example--contemplate what a million+ parasites chomping away on your intestines might do?
Inflammation? Diarrhea as your body desperately tries to rid itself of the vicious chompers? Do you suppose it would hurt?? Or bleed?? Voila' Crohn's disease. That's just the start. Read her book.
And if your parasites are this bad at your age--just think what they must be like at an older age where they've had years to multiply? It depends on the toxins or worms where they end up so you may or may not have the same symptoms aka diseases. But a body infested with parasites sounds exactly like your mother's unfortunately. :(
The toxicity of your current situation would only cause them to flourish and spread faster. Your dad is very much at risk there.
And any agency who gives money to the needy, counts it a financial success anymore if they can drive you away. They count on you giving up---just keep going back and back until they realize you mean it, and they're going to see your smiling face as often as possible for the rest of their careers if they don't actually do their job. Remember you only can win, if you don't quit.
Can you go to another office in a neighboring town? And did you ever ask to see a supervisor? They don't like to be bothered (cuts into their coffee drinking time) so such requests usually get a better response just so you stop bothering them---just keep going higher and higher. They hate that.
Just remain resolute and calm and insistent. Don't let them bully you out of what you need to get back on your feet. Because you will, if you deparasite.
You may need to throw in some herbs (with a hot beverage or as a tea if you can stand the taste)for killing the infections they carry but compared to all the horrendous meds you must be on now, it'll seem like a breeze.
