there to many yoi and yuri mangas but i was looking for samething series
bulling , angry parents a more of that kind of things not just sex and romance

Well, that's a very broad request but here are a few works that are not centred around the love and whatnot, or at least also deal with the things you mention:

Little Butterfly (abuse)
Cut
Konbini-kun (bullying)
Tetsu x Rika
Giglio (sexual abuse ≠ parents really twisted)
Kanashii Doubutsu (some bullying elements)
Koujitsusei no Tobira (sci-fi maybe? ahah)
Nanadome no Gomenne (abuse and incest)
Bokura wa Sore o Hitei Dekinai (bullying)
Bi no Isu chapter 1 - 3 (yakuza world) and the (great) sequel Kobi no Kyoujin
NightS and sequel (yakuza world, kinda)
Saezuru Tori wa Habatakanai
Kimi no Iru Sekai Shikairanai (abused by brother)
≠ - Not Equal (it's just different from anything else; incest)
Sora o Daite Oyasumi this is really, really good (has everything!)

I'm missing a lot of titles probably....

It's the Art of Time, it's the Art of Life--
Of the player and the craftsman,
Of the writer of songs, of the creator of love,
Of those who will follow, of those who led,
There's no other way in the world ahead ♥

As I recall, both Gravitation and Haru wo Daite Ita dealt with the characters making their relationship public, and dealing with the problems that caused.

You might be more likely to find your topic outside BL.
Antique Bakery
Otona no Mondai
Banana Bread Pudding
Claudine...! - shoujo-ai

Also try these categories:
LGBT Character in a Non-BL/GL Manga
Realistic Homosexual Relationship/s
Coming Out of the Closet
Bullying - you could screen this one for yaoi.
