First for the cover up tips, there is actually an article on TH
it wont let me post the link but if you go to this old thread, the article link is on there
have a look at that, theres lots of different ideas.
Seeing as your family have started to notice, instead of shrugging it off, why don't you talk to them about it, see if you can get some help
or have a look at the alternatives thread when you feel triggered
Take care x
