well, i'm one of those people you mentioned that don't offer help and just say "go practice more". but you seem pretty desperate and seem like you're willing to learn, so i suppose i can give you some tips on how to better yourself. although, ichipoo already did a fair job of doing it
1. learn the basics of your character; i.e. high/low attacks and the fundamental combos. i always try to learn the most damaging but plausible combos first
2. learn to block. VERY IMPORTANT
3. my last advice is play others who are on your level or slightly above your level first. then work your way up
believe me, when i first started bb. i was god awful but doing the above turned me into the CT jin hero....of netplay anyway lol
