Man, I can understand the stress. I actually have a similar thing about pictures of me online or anything. I've gotten slightly better about it but I still obsess.
Finding something that will help with your sleep should be of the utmost importance. Strange, my severe anxiety attacks have been waking me up, too. I've been very stressed out lately, also. I think that maybe with all of the stress that came from getting your house, anxiety tagged along and wants to stay. Hopefully, now that the process is finished, the anxiety will begin to lift and you can sleep, again.
Your realtor sounds like a really good person. I'm glad she came into your life.
