Wow.. Great poem dude.. I used to be like that, my parents got divorced while i was 5 lost my youngest sister *1 yr old* when I was 12 aswell as one of my best friends. I used to have horrible anger problems due to holding all that sadness/anger/confusion in but that really didnt do anything good for me.. all it did was make me even more sad. You should find someone to talk to maybe a therpist (thats what I did) and it really helps.

Well I wish you the best.
Great job again.
