I'm a 5'6, 135lb man. And I do not know why people are fearful when there is nothing to be afriad of, just in general.
Whether it's irrational fears or rational fears that you are giving too much energy to, I dunno why you bother. How bad are you really ready for life to get? Maybe that is the question -- I'm prepared for it to be quite crap and still be able to walk away with a learning experience, no matter what happens. Frankly the only thing that I think would really fuck me over is rape, that would be a really tough one to get past. But I think I would probably even the score before killing myself.
You see? I'm going no matter what, because fear is a disgusting thing to feel when it's not neccessary and I don't tolerate it. Get on with your life and enjoy yourself, the forest is safer than the street.
