Can I? (no reason part)

Invite me for your life, let me be part of it. Start the conversation, let me know if you want to hear my voice. Unfortaly I work in this way, I’m not allowed to exist for you if you don’t let me do it. I’m too much afraid to receive “no” as answer, my ego and my self esteem it’s broken because I pass my entire life being something completely out of “the right”. People used to call me for disgusting names, hit me for no reason, put me in a very uncomfortable place and because of that I create some kind of shield for protect me. Now this shield already consume me in your darkness. I need to come out. But… Can I?
