Idontknow

So uhm, well I dont really know what's all happening around me. I know that something is wrong with me, I just dont know what... I feel certain emotions that I can't grasp. I understand the emotions, but I dont know why or how I've gotten them. It's weird to feel that all of a sudden... I thought I had passed that point, but it seems to have come back to me and chase me all around where ever I go. I wish I could just take a step back so it would go away, but that didn't really help. So now I'm just trying to ignore and/or avoid the feeling and the person(s) involved a bit and see if that helps...
Also lately, I haven't felt any extreme emotions (alot of anger, extreme happiness, great sadness) it's like my mind is getting numb for certain feelings. My brain is shutting down, and i feel nothing. nothing except for that 1 emotion that I dont want to have. But without any feelings/emotions, am I still a human, am I still alive or is this all a dream?
