What could be wrong with me?

These symptoms started about 5 years ago directly after a camping trip and after about 1 year and a half they sort of went away (or I got used to them more). However, the past year they seem to have returned with a vengeance and are really affecting me. I have literally no motivation to do anything, and on my days off (even with enough sleep) I am sluggish, tired, and unmotivated.

My biggest symptoms include:

- Severely constipated (chronic)

- Dry hair, scalp/face, and diffuse hair loss on scalp, and eyebrow hair loss

- Bad gas right after eating

- Undigested food in stool (sometimes vegetables, sometimes what looks like white seeds)

- Lack of motivation, brain fog, mental fatigue etc...

- Bloated after eating

- CONSTANT hunger (prefer Sugar & carbs), especially at night, but I always need to snack even in between meals.

- Powerfully hard heartbeat that keeps me up at night at times, I can feel the

entire bed vibrate from it
- Decreased motor skills, from coordination to talking

- Acid Reflux / Acidic feeling stomach

- Loss of libido (has only come on in the past few weeks)

- Very bad breath, and incredibly dry mouth especially in the morning

- Muscles twitch all over from head to toe, randomly throughout the day

- Recently, oral thrush (I don't think Candida started these symptoms, back when they started I had never taken anti-biotics in my life that I can remember and ate reasonably well. Nobody in my family has been unhealthy besides me).

Some general things about me:

- Don't have any weight issues, always have been very skinny and still am. I try to put on weight (I work out A LOT) but fail to do so, regardless of eating a ton.

- I have 3-4 Amalgam fillings, 1 of which is from a broken molar and has been broken for a couple years (but after my symptoms first showed)

My symptoms first began after a camping trip, where after I was constipated immediately upon returning home and couldn't normalize my BM's with laxatives. I was convinced I had contracted lyme somehow and was tested vigorously for it, but apparently I was wrong. Since my symptoms first hit me years ago I have seen many doctors. I have had blood tests, a colonoscopy, and x-rays/ultrasounds. My thyroid levels have apparently been normal when tested, although I am not sure which test they used.

If any of this sounds familiar, please let me know about your experiences with

this. Thank you!
