Awww Leeds I'm the same... I rarely open up to anyone and just put on a smiley face. I've gotten better recently and have actually forced myself to tell people when i'm not happy but I still find it very hard to do and I hate crying in front of people or anything that I percieve might make me look vulnerable. The only reason I've been able to do that tho was cause I went through some stuff last year which I just couldn't hide so loads of people would catch me crying randomly.I think for me it's a control thing so I'm now trying to let that side of me go a little more, it's hard but I'm slowly but surely getting there. And the fact is that your friends and family want to be there for you when you're having a hard time in the same way you're most likely there for them, I'm only just learning that now. Good luck to you, I hope it all works out for you xx
