STOP PLEASE

IM SO CONFUSED OF MYSELF NOW. on and off i feel nausea and gastric cramps. taken the medicine doesnt seems to have any effect and i have unexplainable feeling in my stomach. why is this happening? im so sick of it. the feeling is too tormenting for me. i had endure this for more than a month, why isnt there any improvement in me? im so scared that it might have other causes. throughout this period, i had not seen myself smiling or laughing or on a happy mood. everyday to me is so tormenting, with false smile, acting to be strong, tears and getting slimmer by days. i just want to my health back, my smile back, and the happy go lucky me back. everyone had been saying i changed during this period. had not really been talking, doing the things i like or being my usual self. always facing the notebook or staring at it and will lock myself in the room the whole day except meals time. IM LOST, I NEED TO BRING MYSELF BACK, BUT IT SEEMS TO BE DIFFICULT. and tomorrow will be the day of my report from the doctor. GOD BLESS ME. I DONT WANT ANY MORE SICKNESS. PLEASE.
