Ugh. Yikes

So a few weeks ago, I found out we had bed bugs. So I did the whole bagging up everything and washing it all in hot water, I bleached my whole house and sprayed my mattress down with bed bug spray. They were all gone! No eggs were left over nothing. But today, I found another bug. I've been sleeping on the couch because I am just so paranoid of the bugs. I already have a new bed I just have to get it to my house and nobody is willing to help me. -_- and I'm pretty sure my boyfriend won't let me throw the bed away until I have the new one up here. Any advice? I'm literally paranoid.
