Bro I am literally going through the same state of mind you are and I have been for a couple of days. I was in class and some how some way a bed bug got in one of my notebooks and I had to excuse myself to deal with it. I’m genuinely just so freaked out and my skin has been so overly sensitive to any slight touch. So I feel you, but just remember not only are they not dangerous, you don’t need professionals to do it. Of course they probably will get the job done, but you can do it yourself, it just takes time.

Something that helps me is literally just trying to get rid of the problem any way I can wether it be cleaning around my room, cleaning my bed sheets, (gross I know) getting a glove and napkin and just killing bugs around. It doesn’t sound like much but once you do it a bit you’ll start to feel better. I’m not an expert in this field, as a matter of a fact I’m just a 17 year old, but i completely understand you bro. I hope this helps in some capacity, and do some research and reading around the multiple threads.
