short version this can be just about any mental or physical or normal problem. if you googled your symptoms you would find billions upon billions of things this could be. unfortunately we can not tell you what this is is you (make a diagnosis) for that you will need to contact a treatment provider in your off line location.. can this happen again only you and your treatment provider can say that. with some people yes and with other no.

my suggestion if this continues to bother contact your or a treatment provider ie a psychiatrist, medical docor or other mental health treatment provider.
