I feel down

all the way down, it's been a few really nasty days, since I discussed with my dad about something of not ths big matter, just a high importance school work I didn't told him about and his great fears about me not entering college. And it was influenced by me playing on-line quake2 right before he asked me in a quite rude voicetone to go where he was... sincwe then, I think we've spoken like 5 words each other in this 3 days or somethin'... it is sad to see how a relationship, no matter how strong it is, can be mostly broken for something that is not a really whole important thing....
what is worse, this situation makes me feeling good while I am at school, and that is weird and unhealthy in any guy...
