You shape your own reality. You can feed yourself with lies that someone else can make decisions for you but you are the only one who can make decisions for yourself. Isn't it your decision to let other people affect your life ? You can alway change that and take control. I as well have dreams and goals that my parents don't understand and don't believe in me, but I don't let that affect me not a single bit. I still keep taking action towards my goals!
