I'm a mixture of both, When im happy, i'm really happy but when i'm down....God i'm just absolutely awful! The worst bit about it is that i can see what i'm being like, but just don't want to stop, kinda enjoy it...WIERD!!! then i give my head a wobble shake myself out of it and think what have my supportive boyfriend and 3year old son done to deserve it...nothing, so then i snap out of it!
