I agree with you. Almost all your symptoms are those of Kundalini awakening.
You do need a good and a realised GURU.
However you must read a few books by Psychiatrists from west who have studied the Kundalini process. One of the best is Late Gopi chand from Jammu.
He describes all his negative{Pingla, hyperactive and burning hell, Rajsik} and positive (Sushumna, Satvik) and (ida, Tamsik and depression) experiences.
If you do reiki use massage hourly (skin is the biggest organ) to generate somrasa(endorphins) that will help you.Eat good food every hour in moderation.
But read and introspect but for short while only. Go for long walks.Be in a saxibhawa. Practice awareness. Concentrate on own breathing with full awareness.
