stop period completely

Ok so I know having a period is natural but I honestly can't handle it. I have pretty severe anxiety so I am worried about it before it comes, thinking it will come and I won't notice, afraid of stains on my pants,everything. I am worried during it and  freaked out after it. So having my period is a 24/7, all month, all year,  forever thing that I am worried and freaked out about and scared of and I so sick of it, I brought it up to my doctor and she said there is nothing to do about it, I am already and anxiety medication but it pretty much does nothing. Some times during my period I have so many panic attacks about it I have to stay home from school. I really want it to just go away completely.
