I am so sorry you're feeling so scared. Trust me I have been there.

I let my emet hold me back from going and getting the true college experience which I regret. Instead I went into the working world (but did very well!) and just finished my associates degree in my early 20's and am now starting the rest of my bachelor's in the fall. I can tell you that whether you go to college or just go to work or have a roommate or don't have a roommate the same events are going to happen: you're going to drink from a water fountain, open a door, touch a surface, or use a restroom that someone with the SV used and may/may not have germs on it. Regardless of having a roommate or being in college or not these things will happen.

I was on campus this fall and winter through an awful outbreak in my area of the SV using public bathrooms and even going to the gym at my schol 5x a week but never got SV. I washed my hands frequently, didn't touch my face EVER, and kept sanitizer on me as well.

With the drinking, I was never a big drinker because I was afraid it would make me V*. I have never done that from drinking because I never drink "too much". I actually enjoy a strong drink or a good wine with dinners out because it gives me hope that if there's some food borne illness in the food prepared for me, the alcohol may help kill some of it off. It also tends to make me relax a little.

Having kids is my biggest dream for my future and I agree - it scares me to think that they could come home with the SV and I could get it - or heck, even morning sickness scares me! I try to remember that adults generally have a better immune system than kids. My brother got the SV a lot as a child and my dad NEVER got it from him and my mom very rarely (maybe once?) contracted it. You're still so young so I am hopeful for you (and me!) that before we have kids we will get our fears under control!

I know this is cliche because I am dealing with it now, but try not to let it hold you back from your whole life and seek therapy. I am seeing a therapist via my school right now and she's really helping. More than anything it just feels good to speak with someone face to face about your fears without being judged.
