TTP I have to commend you. You have handled a difficult situation very well. You have been very clear to not blame your doctor and to also give a completely honest assessment of your results and how you feel about them.
I have had 2 HTs, met numerous patients and researched Hts for years meeting many HT doctors along the way. So I think I am an informed patient.
The proof is in the pudding and at 10 months it is very reasonable to expect to see more growth than you have. Personally I would be unhappy too. I would be unhappy with the growth, the doctor's assessment and the implication that somehow it is physiology and/or unrealistic expectations.
I just wanted to give my opinion and I really do hope things improve for you over the next 2 months.
