Had some of the same, what worked for me, i did 1 parasite cleanse, 2 liver flush(clark) several in few months, 3 start fast(juice)more easy going, more short fasts are easier aprox 10 days, use plentifull herbs read up or ask, and learn what is good food and what is not.!
Your mind seems quite capable for the journey research what to expect, and be sure to keep those bowels moving thats hard while fasting, look for lbb that will do just fine.
Take these steps 123 worked for me anyhows ,with quite some time in between for recovery and let your body adjust to the situation, can be a litle rough sometimes but will get better with time have some pations.
After with more or less clarity/peace of mind/body research further, live and learn, how high do you climb?
