I clean a lot with bleach.... i tend to isolate myself in the bathroom with the smell of it and other supplies unventilated. is it harmful to me?

It may: Any chemical in excess can be dangerous. The other issue is: 1. why do you spend so much time cleaning?? 2. why do isolate yourself in the bathroom? It seems to me you might benefit form some counseling. Good luck

Yes, absolutely!: Chlorine bleach is corrosive and can even damage metals. Its toxic fumes can cause respiratory problems, asthma flares, headaches and vomiting. It is especially hazardous - even deadly - when mixed with ammonia, vinegar or any other acid-type cleaning material. And these fumes are especially dangerous to children.You must get ventilation and limit your exposure when using bleach. Hope that helps.
