Diet when it comes to parasites

Can you get rid of parasites?
If we will have them forever can someone give me some advices on how to live?

I have a past of eating distorders and the last 10 months of trying to get rid of parasites have left me depressed and I wish I didn't have to eat.

I fought so hard to get out of my ED and now it feels like I'm sleepwalking back into it.

HOW important is diet?
Obviously refined Sugar but how about grains, fruits, dades, honey etc? Some dairy and gluten occansially?

I'm 23. My symtoms are massively reduced now. I've never had stomach problems but I HAD I insomnia, eye twitch, backpain, nervousness.

Now I sleep like a baby and my backpain is gone most of the time.

I feel like I'm missing out on my youth now when I'm even afraid of eating out (in case that sallad wasn't washed), drinking water, using flour toothpaste, touching things. I feel quilt having alcohol so I haven't been out with my friends for a year soon.
Someone please help me, I'm starting to get really depressed
