I think it's a common thing to do. I've done it my whole life, and people that aren't that close to me get such a shock when I tell them I'm unwell or how many years I've lived with it. There's nothing wrong with seeking help, also it can help to put on that 'mask' some of the time, but if it builds up too much it can just blow up. Which has recently happened to me again.

I do hope you have some support though, going through these illnesses alone is near impossible.
