friends

In these two days, i saw a film called Summer Times and a series called K.O Class No.1, both of which are concerned about a theme of friendship. The first one is about two boys live together until the age they go to college. Always, we can guess where their feelings will go. One boy has loved one boy, when he come out, the other boy said, " we are friends, i can accept you." At the moment, i was crying. i don't know why, i just want to make sure if they're reall friends and what's the definition of friend. i ask myself for thousands of times, but i still can't find out the answers and i'm still confused.
In the series, the actor DaDong said," I'll never bit my friends." So how about you? I'm not sure of myself on that point. I just want they would not betray me. And don't make any rumor about me. I think that's enough. So who can understand me? Who can trust me and whom should i trust?
I lost my way in my life. I don't know where i should go.
