Help for my family, I thing we have Ascaris

I'm a newbie here but I have been reading through this forum for a few months. I really need some advise on what to do. A little back round on my story. I'm 39 with 2 kids 8 and 10. The last 2 1/2 years or so I stared getting sick with nausea, stomach rumbling, bloated, losing weight for no reason and my whole family started to get tingling in our legs. I've also had hair loss, Acne since teenager and pain in my right upper quad for at least 4 years. Like everyone here,I went to my Dr. have had tons of test from then till now and no answers. Only thing was low b12 and vit d. I've seen gastro, nuerologist, rheumatologist, chiro and nothing. I have good insurance which now I know means they will not help me. I did suggest maybe it could be parasites and they said no that doesn't happen here. I took a stool test 2 times that came out neg. I saw a ND 2 yrs ago and I did get better but not completely . She gave me drops , vitamins and I did to a herbal parasite cleanse with Black-Walnut , Wormwood and cloves. I got a little better but then I couldn't afford because I my kids were getting sick and I had to take them instead. My kids where getting headaches, stomach aches and dry cough, dry eyes, leg pain and always tired. I had my house checked for mold because at first I thought it was that because we had moved recently, but it was fine. My kids got a little better but I didn't see much improvement so I had to stop going because of cost. Now fast forwards to today I have been having lots of muscle aches especially my calves,eyelid twitching, weird skin sensations on my face,memory loss, tingling on my legs(on and off for 2 years) twitching, jerking, don't sleep well, shortness of breath especially when I'm trying to go to sleep, my arms and legs fall asleep really quik like bad circulation, and I get shaky sometimes. I am taking spirulina, msm,magnesium,vit c,q10 but don't know if I'm taking enough. I think I have Ascaris from what I have read but not 100% sure. My kids have been fatigued all the time,stomach aches, wake up at night,constipation, one son has been seeing black spots. I just took him to the optometrist but they didn't find anything wrong. Also they have dry, itchy eyes, my younger son has learning problems, headaches and bloody nose I'm sure there's more but mainly that. I have them taking probiotics and vit c and papaya enzyme and multi vit. I forgot to mention when we all started getting sick we had what looked like seasame seed looking things in our stool , that was whe I did stool test for my son but came out negative. I recently tried pin x and it did seem to help a little but my symptoms are pretty much still there. Maybe I need to do more often, have done it 2x 3 weeks apart. I'm just scared to try meds on the internet but I thing I might have to. I just don't know what to do about my kids. I know what I have is contagious because now I've noticed other family members with symptoms as well that don't even live w/ me. I also had some thyroid issue but didn't take any meds just keeped monitoring it and it seems to have gotten better on it's own. My husband also had thyroid issues. Sorry so long just trying to give as much info as possible. Please any advised would be greatly appreciated. I get so worried for my kids and myself because I need to be able to take care of them. I do have a husband that is supportive . I'm not good with writing so please forgive my writing is kind of all over the place. I get so overwhelmed with so many options I have read here and don't know where to start. If you have any advice on what I can give my kids, I don't want to make things worse for them. Thank you.
