Scared to get my period?

For the last year or so I have literally been afraid of having my period. I get really nervous and I'm afraid that I will never stop bleeding. I know this isn't logical thinking and I know that it will stop I just get very bad cramps and I feel absolutely disgusting when I get it. My ex boyfriend used to make fun of me when I'd get it which I think contributed to me being scared about it. I don't know what to do, I've been having periods for five years I feel like there is something wrong with me.
