Welcome to the forums, yes I have been there and worse, the only thing I can offer for help is to get some mental health professional advice if this has carried on more than 3 weeks, you can start by asking your GP for a referral, also before that have a physical to rule out any physical things that may be making you feel this way.
I wish you lots of luck with this and feel free always to come here and talk, or go to "chat".
