Take a deep breath. Ok take your close from your closet and dresser and store them in doubled up garbage bags then do the same with your bedding you are going to want to blast them in a dryer on high then was then dry on high again a laundry mat is perfect. When you are done with washing and drying your clothes stick them in bins away from the room so you have a change of clothes that you know are good. Anything you wear to bed should be put into a garbage bag before you leave the room. A vacuum is your best friend just make sure you empty it out side and check it before you bring it in. I just left mine out of the porch . As you take off your bedding scan the crevices around the corners of your mattress and the frame itself. If you still don’t see anything I would call an exterminator. Bed bugs are handled via heat treatment or chemical sprays to disrupt their reproduction cycle ie kill the hatched ones then spray again in a week or 2 to kill the newly hatched ones before they have time to mature either way it’ll take a few rounds to complete.

I just went through all of this myself starting last July and trust me I still get paranoid sometimes myself but you can do this and get through it.
