Anybody identify with the following?

[feeblefreda]

I was always shy and introverted but never anxious until now, my middle years (don't ask!) Since my father died I have been aware I have desended into OCD, checking things a multitude of times and convinced I have still made a terrible mistake which will have dire consequences for everybody concerned. I make a decision then instantly regret it, ie, I have put my house up for sale more than once but never had the nerve to finally sell and move. I book to go on holiday then instantly visualise all kinds of horrors, so don't go. My comfort zone, to use the modern parlance, becomes ever smaller
