I've had depression for about 18 years now. It's treated with meds and I live a relatively normal life. This is going to sound such a strange story but a few weeks ago, there was a bug in my bedroom that I took a photo of and a few people told me it was a cockroach. It actually turns out that it probably wasn't but ever since then I have a ridiculous bug paranoia that I can't seem to shake. I don't sleep in my bedroom and have gone from someone who used to enjoy being in bed to someone who sleeps merely because I have to. When I thought I may have a cockroach problem I read a lot online and stumbled across a lot of information about bed bugs. I then developed a stupid paranoia that I have them which I can't shake though the last couple of days I've more moved on to bird mites. There is no logical reason for me to have these things and my symptoms have only developed since the bug incident but my skin feels like things are crawling on it all the time. I've had literally a couple of bites but it's been a hot summer here in the ok so not exactly unusual. I certainly do not have enough bites IMO to warrant these suspicions. I do have some pin prick like red marks but I don't know if they've always been there because I've never constantly inspected my skin like this before. My question is - is it possible these symptoms are a being caused by my mind? Can the mind really produce physical symptoms like that? And if so does that mean I'm suffering from some kind of psychosis. Any help and ideas would be greatly appreciated. I really don't know if I need pest control or a doctor.
