@GuiltyBoy,
In attempt to understand what makes you feel guilty about what most of us consider perfectly normal feelings, as I had queried please tell us something about yourself beyond what we already know; that you're a boy of 18
..such as nationality, education, family, acquaintances etc
Clearly you've been left out of things in some critical respect and while we'd like to help you, we'd have to know more about your upbringing and circumstance
