I'm really scared of myself

I'm scared of myself lately... I want to go to an psychologist, but I don't think there is something wrong with me. I just want to talk to someone, but I don't know how. I'm really tired of my life. tired with my struggles, and what I'm supose to do. But I don't want to die, not yet. well... I strangled my rabbit becouse I was bored, and I told my friend. but she keeps talking about it and brings it up every now and then. it makes me uncomfortable. please, can someone tell me what to do? why do I feel this way? is it... normal?
