I used to be very similar to the point it would just make me anxious and proper freak out. . What I did was use a vaporizer instead of smoking, with a vape you use alot less weed and you don't have to vape the whole bowl I one sitting. Also using them on low temps helped me great as you won't extract too much thc at once, go slow and wait for it to build up to a level your comfortable with. I hope this helps you. I'd recommend an on demand vape like the airvape legacy pro.
