Too much to ask?

Im so tired to keep up with this, I don't have whatever it takes to become what you want me to be. I dont dare to step out of the line fearing u saying Ive changed, so I kept it in. I dont blame for what you did, but Im so tired of chasing that line knowing I can never reach even if I try to. And the saddest part of all is the feeling that I dont belong here anymore. I dont want you to give up on me, but at the same time I wish you understand I need my space , and I can deal with me and my own life.
