Looks like a brown recluse. You can see the fiddle on its back. They typically don't hurt when they bite but symptoms develop over time. Monitor yourself over the coming hours and go see a doctor if you develop concerning symptoms. Not everyone develops bad symptoms from a bite, so don't worry too much.
Good luck anon. Glad you took one of them fucker out.
