Recently my family visited my brother's home with our dog and unfortunately came across ticks. My dog wears a small shirt and we saw one (a nymph) crawling on her shirt. We took it off and checked her but didn't find anything. I am someone with very extreme anxiety about ticks. I have bad anxiety in general but ticks are something that scare me so bad. 

Fast forward to last night when I was in my brother's home and found another nymph crawling along my blanket. Immediately I was freaking out. I felt like they were just all over me at that point. We left early to come home from our trip because of it and I got a shower immediately. I checked my body for anything and didn't find anything, but am still worried about something being in my hair. 

We bathed our dog and unfortunately found two ticks on her. Another nymph and one that sort of looked like it had been feeding for a bit, both at the same entrypoint. I stepped up and was the one to remove them, but have been feeling sick and lightheaded since this whole thing started and it's taken a lot out of me to calm myself down to the point where I don't faint. I've felt like I was on the verge of it for a couple times now.

Here is where I need the advice. I am freaking out thinking they're on me now. On our things. On my dog even more than what we found. Are they going to fall off and attach on us in the home?  Are they going to lay eggs inside our house and cause an infestation? Can they crawl from my dog and go on us instead??

These questions have been running through my mind all night long. It may seem like such an overreaction but they are something that have really scared me for most of my life. I havent been able to get any sleep and I'm scratching my body so much that I've begun to practically give myself marks from how hard I'm just panicing and itching THINKING that somethings on me. I also had lice as a kid and that's traumatized me to these small pests that I'm just freaking out.

I've cross posted this on thr r/DogAdvice subreddit to get more help for my dog on her side, but here I think I need more help for myself. I haven't been able to calm myself down since this happened and know ticks aren't a big deal to hunters and more woodsy people, but I haven't really had much experience with this and already have a massive phobia about bugs. Every black speck, every hair brushing against me, every little think I used when I was visiting my brothers house I'm having trouble using again thinking there's something on there. I need some kind of help because I cannot live like this

Tl;dr: dog caught ticks, major anxiety causing panic, how to help calm my mind about these pests
