I need help. Please have a look at it!

Hello doctor, I really need a expert's advice for my problem. Earlier I had extraordinary remembering capacity but from 6-7 months my capacity to remember things for long has been declining at huge rate. In class 10 boards I scored good marks and wanted to go to kota for IIT preparation. We don't have a good coaching in Assam. I was admitted to a coaching which I didn't like at all because they were befooling us by teaching only boards syllabus they took 89k for one year and said that they will be teaching us for jee. I tried to get out of the coaching( 9-10 times )but failed every time. And under my parents presure I had to remain in the same coaching. Many times I had suicidal thought But the only thing which kept me motivated was the thought that I will get out of it in 5months I am not able to properly express my concern and therefore no one believes me.I really don't know what to do. Due to word limit in practo I am attaching my concerns with my reports please have a look at it
