Want to cleanse my 17 yr old.

but I have some questions first. She has always, since about age 7 had bowel movements that quite frequently clog the toilet because they are so big. I beleive she has flukes because at an early age, at times when I would have to clear out the toilet I would see the tomato skin looking stuff in the toilet, sometimes floating sometimes in the stool. I never knew what it was but was always baffled because she doesn't even eat tomatoes. She hates them.

At age 9 she developed severe cystic acne which during that time we have done every cream antibiotic and everything else ending with the dreaded accutane which gave her suicidal thoughts so we stopped 2 months into treatment. Since that, she has complained of occasional pains in the upper left side of her abdomen. Just below the ribcage. I'm thinking colon issues? I am so new to this. I have literally just started reading everything on this site about 3 weeks ago and am learning so much. She eats terribly! Not MUCH I can do about it because she is 17. She is out quite frequently when she eats and my husband thinks all of this stuff is a bunch of hooey so he won't adjust what he buys so I am also becoming concerned with my younger kids. My 8 year old seems to be developing digestive issues. My house is full of sugar. Not my fault. My husband does most of the grocery shopping. Anyway, back to my daughter. "They" have determined that her acne is hereditary and there is not much else that can be done. We are thousands of dollars into microderm and I can't afford to keep it going. Twice a week they want to do microderm which we have done since February. My child support ends this month and I can't pay for it. I think her acne is caused by parasites. Any opinions on this? Also, what could I do to prepare her for the parasite cleanse? I know she will suffer severe die off because I think she is severely infested. She gets migraines, has no energy, has TERRIBLE body odor but is not fat at all beleive it or not. Anyway sorry this is so long but I wanted to give you all the details for a more accurate answer. Based on her syptoms as well, what do you all think she is infested with?
Thanks,
Joy
