Is there any chance of getting a sooner appointment?
Thing is, each block of counselling works differently - it may not work, then you go at a different time with a different person and it suddenly clicks... It's always worth trying again.
Hiding things from your doctor is like trying to do a jigsaw puzzle with only a % of the pieces. If you don't tell them everything they can't help with the most appropriate meds, treatment, options....
I can't say for sure whether you will or will not be sectioned - I'm not qualified to make that decision, but it does sound like you need more help than you are having....
