It is a complete nightmare situation to be in, no one knows that better than the people on this forum.
I think you should post back with a bit more information. For example what the odour smells of, if there are any types of food that make it worse, when it started, what your diet is like and anything else that you think might be relevant. This will help us try and work out what the cause of the odour might be and then you can work how to get rid of it.
Things are really hard but you refer to yourself as beautiful26 because you are beautiful and no one can take that away from you.
The people that are abusing you do not have the right to say any of those things to you. Remember that and just take one day at a time.
