I feel sick to my stomach about getting an STD

I feel absolutely disgusting. Not only did the guy lie to me (saying he wasn’t sleeping around) and give me chlamydia he also gave me the virus that causes cold sores, HSV! I am completely devastated. My mother gets them and I have always been incredibly thankful to not get them but now because of a liar I do. And it will never go away. I’ve never had one before and I am so terrified of getting one I feel sick. I’m glad that the std can go away but I still feel like my life has been impacted greatly and I have not been able to stop crying. How do I get over this feeling?
