MY PARENTS DON'T LIKE AT ALL THAT I'M OBSESSED WITH ANIME.. HELP ASAP!

Honestly if you're living with your parents, you need to compromise. Watch all the anime you need to, I'm glad that it helps you. At the same time it's not great to have all your mental stability eggs placed solely in the anime basket and I bet your parents realize that. Either move out or keep your love and what it sounds like dependency on anime low key. Explain to them that it helps and i bet they'll compromise. At the same time they're probably worried you're largely dependant on something you shouldn't be.

i like that graf MO users hitting with FACTS and LOGIC

don't be obsessed with anything poof problems gone

+1 to Charles there as I agree 100% I'd also like to add a bit on home decoration in general. If you go way hard in the paint plastering your walls in anime you're going to make an impression on others that come into your home that could be overpowering or negative. If you do a nod towards your interests with a few items here and there you still get that warm fuzzy feeling in your tummy looking at them, but don't put off your company either. It also leaves more room for OTHER interests you have to decorate the place up with. Eventually you will probably have a coworker, a friend in need, or a special person come over for a first impression and you do not want to give them the heebie jeebies. Again, not saying 'hide your passion', just... moderation. :) And finally, if you do go out and buy rooms worth of otaku stuff (like I did once upon the day), years later you will have outdated otaku stuff that you might have just bought in the thrill of the moment to cover a wall and you'll need to get rid of it. It's just too heartbreaking to throw it away, and finding other un-decorated anime houses is a hard thing to find.
