I got bit by a spider and don't know what to do?

I rummaged around in my closet yesterday and "disturbed" the spiders I am guessing. I killed a brown spider yesterday on my bed that was brown with long legs about and inch and a half long. Long legs! Now I have a "circular" reddish ring about the size of a quarter below my belly button with what appears to be a "blister" in the center, a raised "sac" just like a blister that hasn't been popped. Put alcohol on it and still have ice pack on it as it was somewhat painful. But really do not want to die from a spider bite. That's just not good for me! LOL I live in western Kentucky and supposedly brown recluse spiders are bad here, though the landlord (I live in govt housing project but it is a small nice one) sprays monthly for bugs and stuff but I don't allow them to spray in my bedroom as it is usually messy! LOL No I am not a hoarder but it seems like everything that my daughter doesn't want anymore ends up in my room! Though not blaming her for this. I just want to make sure that I don't die so if you don't hear from me anymore, you at least will know why! Anybody know about spider bites? This happened several hours ago or probably as I slept and no symptoms as yet except the bite itself. Thank you for any help. Would appreciate it!
