What possibility is there for mental sanity when BED BUGS are present?

I just moved into an NYC apartment. I am sleeping on an air mattress, and nightly, being ravaged by bed bugs. I have washed/dried my clothes and bagged them. The exterminator is coming for the 2nd time in a few days. I JUST finally saw one for the first time, crawling on a sweatshirt I JUST washed. I am in hell. My body is covered with bites, both itchy and unsightly. I can’t sleep. They are gross. Will this ever end?!?!?
