Welcome to HCM
We understand your concerns
I went through your problem description. I suggest you not to worry too much. I can assure you that you have no problem physically. The only thing I can suggest you that you are being lazy. You are not interersted in your studies. You are just living for somebody, not for yourself.
Lazy people do sleep in excess. They loose interest in worldly affairs. They eat less food. The are inactive and therefore not agile. They forget because they don't want to remember anything. They don't learn because they don't understand why they are learning. Over and above they always complain about they have some physical or mental problems which even doctors could not find out.
All the above description fits
and you are lazy. You need psychological counseling
. I can provide you telephone psychological counseling through www.healthcaremagic.com. Contact me through customer care team.
Hope this answers your query. Available for further clarifications.
Good luck. Be active.
