Thanks for the response Rapunzel

I am sure it is very likely that there is some form of link.

The only thing that springs to mind, in terms of child-hood comfort-ritual, is the fact that whenever I was distressed...which was a lot of the time due to, most likely depression from an early age, is that I would lock myself out from the rest of the world. Most of the times, I would keep my self busy with almost totally "un-productive"/"mindless" actions and I would get seriously aggrivated if someone interrupted me.

I still do that in a way now and it might even be that the attempt to get away from that habit, is causing me to try and find alternatives...

Additionally, the change had come very suddenly and very unexpectadly as I was diagnosed earlier this year with Marfans and this most probably has thrown my whole mental state in a mix...which I don't realise.... but thats most likely whole page worth of discussion...
