Depression is a bugger and the slightest thing can set you on a downward slope and no matter what you can’t stop it!, it’s amazing how many replies here indicate towards having some degree of it at some point, just goes to show we are not alone with it even though it feels like it and as much as any forum can annoy for the most part it can bring some enjoyment to things and if you do log in to see all the replies I hope it gives you some solace that we all wish you well and hope you return very soon, all the best John
