Red-ish "raw meat" looking chunks in stool, along with others strange stuff.

Hey Curezone! I've been lurking these forums these past 2 weeks because I'm starting to think I have a parasite infection but never posted before. These last 4 months I've been really tired and sick but also progressively getting worse. I thought this might be a natural reaction due to hormones since I'm in my teen years (17).

Since I live in the western part of the world, Sweden, it's an extremely rare occurrence that your problem is parasites and it's most likely to be the last thing you would suspect. But what really caught my attention was that lately I've had an extremely unpleasant feeling in my anus at night(gross, I know). It feels as if there's a worm squirming there or in my colon area. Along with that these past 2 weeks my stomach has been making some strange noises during the night, along with nausea sometimes in the morning(i feel like I'm going to vomit or have the flu) that goes away during the day. So I did a stool sample and it came back negative. But collecting the stool sample I noticed a thing that looked like a ball of raw meat, but I just shrugged it off and forgot about it.

TL;DR: read below

I'm not feeling different and so I started some light natural remedies such as garlic cloves, cayenne pepper and coconut oil along with a persistent vitamin C intake, to see if I would pass anything parasitic so that I can take it back to my doctor and shove it down his throat for being so skeptical towards me. Jokes aside, I have been doing this for only 4 days and I seem to be passing more of what I mentioned, balls of raw meat is exactly what it looks like, the largest one being of the size of maybe 4 peas combined. I have not eaten anything even close to something like this, and my diet is very very healthy and has been for the past 2 years. I know exactly what I put in my body. So I'm wondering if anyone out there has any idea of what these things could be? I hope I'm not shitting out parts of myself haha!

I would also like to note that in my feces I usually manage to spot maybe 1 - 2 white rice looking thing sitting in my stool, but I'm not a big fan of dissection so I've avoided taking that closer look. But if the amount increases as I keep taking my cayenne and garlic I'll know exactly what type of worm that is.

Would very much appreciate help since I'm more or less being called a insane or a hypochondriac by everyone I talk about this with, and that includes my doctor.
Thanks!

P.S I was in Bulgaria last summer and Cuba 2 summers before that.

UPDATE: I very recently did an enema with warm water and apple vinegar and all hell broke out, there were tons of chunks of those red things, pea sized white floating ant-egg looking things, it was basically a huge barrage of odd shit and I didn't even get to see more than half of it because it was so quick down the toilet. I'm suffering from severe insomnia and I believe it's due to the anxiety these things in my organs are causing, I'm really freaked out by it, please help!
