What can I do about my terrible life?

dude i am sorry about ur mum (dont hate muslims those ones were just mislead) but what you need to do is go clubbing and party hard (no drugs though) work our, improve your looks. and one of the good things about clubbing is that no matter how badly you fail at picking up chicks all u gotta think is that if u get rejected you will learn and you will 99% chance never meet that person again. having a girlfriend (with a good personality not one who will just add to the damage) wil lift your spirits it will give you a purpose to life, you say you love music, it will give you inspiration. height dont matter for most girls it is 95% personality. you just sound like you need a purpose in life, study hard and socialise even harder. just bear with it bro. when you grow up youll have a family and then you will love life.
