I got bitten by a fucking spider and I feel like the world is ending

My husband was out of town for work and I was in bed tonight with my cat at 10 PM and suddenly felt something walking across my chest as I was starting to fall asleep. I thought that it was my cat and I was getting ready to pick her up and set her off the bed when my hand brushed across a spider. I fucking flipped out, and I grabbed my cat and went to the living room, all the lights on to look for it. She was going nuts because I was getting ready to lose my shit and she could tell. We looked all over the bed and nothing, he came home and we looked all over the room and nothing. We think that it was a brown recluse or a wolf spider because it was big and brown with a weird pattern on its abdomen. Now I'm freaking the fuck out about it because I have a history of spiders fucking my shit up. I got stung by a black widow once in 2014 and I think that I got bitten by another black widow when I was a kid. Now I've been researching for the past hour on the different dangerous kinds of spiders in my state and I'm getting ready to lose my fucking mind. I keep thinking of the fucking spider and wondering if it's in bed with me or if it's on me or if I've killed it and I just can't find the skin. I know that I won't sleep and I've been fighting insomnia for months.
