It might seem stupid to others but it certainly isn't stupid to you. Being afraid sometimes is natural, although with anxiety/panic it's driven to an extreme. I've been living with it for almost two years now and I can tell you, it definitely ain't easy. What's important to remember is that there are people you can lean on if the need arises. You said you talked to your parents after the incident, that's great! I like to call my mom if I'm having a particularly bad panic episode myself, or my best friend. A network of support is the foundation you need to lay first and seems you have that down already. Another thing to remember is that you shouldn't be ashamed of what you're going through. I know it's hard, believe me, but it doesn't help your situation. Shame will only make things worse in the long run. Talking with those you trust can really make you put your triggers into perspective. I used to not be able to stay out for long periods of time before panic would set in. Now, I've been away from my home for almost two straight weeks with only minor problems. If you haven't done so, I'd recommend seeing a professional to see what can be done for you. I'm not gonna say meds are gonna magically cure you (I quit using meds myself) but it could help out even if it's not much. Just know that you aren't alone. You can get through anything with the right attitude and a lot of love.
