Please help me !!!!?

Im 17 years old guy and my teachers and family says im dumb. On internship my boss wants to fire me (this is my second week on internship) and my colleague (an another intern like me says I 'm stupid. I have bad grades on school. My drive instructor is holding my down: he says you have 15 lessons and cant drive correctly but other only have 4 and already can drive. My friends never contact me, only if they need me, if they are with girls they dont know me anymore. My family (uncle etc) NEVER send me a message, i didnt saw my dad 6 years and he doesnt ask how are you doing or how is your life. I Play soccer to and my teammates says that im really bad and dont need to come back. I worked on a a supermated and they say to me we dont need slow workers like you. i want to sucide..
