Am I Mentally Ill Or Am I A Normal Teen?

Just to start off I REALLY NEED SOMEONE TO TALK TO my life just really sucks. Now i know what everyone going to say im just a teenager life ill feel like its the end of the world being a teen but it's not. I know okay, but no one knows my whole life story but me it's a very long story but ill cut it short i pretty much grew up well im still growing up with a very controlling, negative, abusive dad and that just ruined my life completely. Now growing up in my house with drugs, police, being abused my life is really a horrible shame. Im treated like a loser sometimes at school im more of a sensitive guy and im usually a big target with friends, im also overweight and that takes a huge part of my life. Now i literally only talk with most people through internet, text messages, and pretty much video games. Now pretty much the only person i have let in my life that i love with all my heart would be my mother but lately shes really been turing on me BAD and im becoming very nervous because of horrible attitude she is giving me (No shes not on her period) shes literally been treating me like crap for many negative reasons i can't evan list that is how many there are, well anyways her and my dad have been saying its because of too much video games thats screwing me up. Well sorry i need to have a social life too. I really wish they both can just be in my shoes one day and feel what its like to be me They have NO clue because if they did im sure they wouldn't treat me like this. Now i wouldn't consider my self as spoiled, arrogant, rude. Im more shy, emotional, and physically tough. I often wouldn't let my anger out at home but somewhere where im alone (Btw I dont cut my self) I PROVED that i could get good grades, i also PROVED i can loose weight by my self but yet they always deny everything i do in life. Well the point im trying to get at is they always use the same god damn term that i need to see a doctor because im mentally ill. I don't evan think they know the real definition to mentally ill and they think by putting me under medical drugs that it will make me more calm. I researched what these pills that for example kids with ADHD go threw they can leave horrible after effects in your life. Anyways the point im trying to get across at is "Am I Mentally Ill" (Or need to take pills or see a doctor) If anything i think it's just their nerves taking it out on me. Anyways is there anyone out there i can really talk to PLEASE i want company i can't live the rest of my life angry and depressed.:( And no im not going to sit down and talk with them because believe me i have tried that many times and it just wont get past there minds.
