Roommate problems...am I blowing this outta proportion?

Okay, so there are some "little" things that really bug me. But all these little things start adding up to one big problem so I wanna tell you all the things my roommates do, and you tell me if I'm overreacting. Roommate A. never helps clean the bathroom and kitchen. He never pitches in for toilet paper and slams his door right next to my room even in the middle of the night. He has a girlfriend that comes over ALL THE TIME so I also have to share my living space with her. Roommate B. lets his dog up on MY couches when I don't even let my own dog up there. He leaves MY t.v. on that I generously donated to the living room. Eats my food and leaves his trash all throughout the house. At least the first roommate confines his trash to his stinky bedroom. Roommate C. is my ex. He's not so bad 'cause I can still tell him what to do but for example, he never makes up the bed. He also never has cleaned the bathroom and he too doesn't pitch in for household necessities. So whaddya think?
