Tom, never ever think you are alone.  There will always be someone here to talk with you when in need.
Several years ago, like something in the order of 30, I spent a couple of months in a psychiatric hospital.  Even today, I have not the faintest idea what the diagnosis was upon my discharge.  What I do know, is that one night, a week or ten days before I was discharged, I wrote something that changed my life forever.  I must admit that I have no recollection or writing it, but was told about it by one of the staff the next morning.
I am now one month out from the end of my treatment.  I have yet to have a post treatment visit with my RO, but have seen my MO.  Thus, I have no clue whether what I have gone through has worked or not.  Yes, that is causing a whole lot of anxiety.  However, reading this thread today brought me back to that time some 20 years ago.  I am glad I read it and thank you for sharing your concern.  It opened my eyes and brought back that phrase that I wrote so long ago.  I would like to share it with you and hope it brings some peace to you, as it has done for me.
Though the future be hidden from me, like a candle in a darkened room, it cannot and will no be found, until a step is taken, or a hand is put forth, by me, today.
The past cannot be changed, as it is history.  All we can do is make our own new history, each and every day.  I will never see tomorrow, for it is always today.  Therefore, I will live for today and make the best history, which will become many yesterdays in time, that I possibly can.
