Need Reassurance- Bug Anxiety & Not Sleeping :(

I believe I have carpet beetles- but the worst part is that I think they infested one or both of my couches and maybe more :( I always find chewed up threads on my couches and pillows, small black pellets on everything and so many holes in my clothes. What I'm worried about is that I move my clothes from my couch to my dresser and closets and now I'm worried that everything might be infested. I have a horrible bug phobia and I haven't slept. I am so anxious and need reassurance. My apartment is sending an exterminator but he usually just sprays the corners and says I'll be fine :(

I really need to feel in control and feel convinced that the bugs are gone. Any tips to ease my anxiety would help. I am literally thinking of throwing all of my furniture and clothes away and just moving because I'm so worried.
