My dear friend,
I'm going to tell you what I think. Some people are scare of going on a plane. So they don't go on trips if they have to get on a plane. But whether they say to people they are scare or they don't feel like travelling or whatever reason, it is their right to say whatever reason they want. It's nobody else business.
A lot of people hides things. It is not only people with mental illnesses that hides. This world is judgemental and can be very cruel. So people protect themselves by not saying really what is going on with them. I do that too and this is one that I don't feel guilty about. I have been hurt too often.
Just like you Myzen, It's your business. If you want to say that you have the flu, well say it. Or any other reason you want. Don't feel guilty about it. You are, in a way, just protecting yourself.
