On the edge

I feel a bit like this tree ... on the edge... ready to topple over.

I am a pain live with ... get like that when I'm stressed... rather than letting people help me, I push them away and get on with stuff myself! I tend to take things out on the people who don't really deserve it ...

Been here many times before and always been ok in the end ... so I'll just get on with it... just don't tell me my shoe lace is undone, it might just send me over the edge ... ;-)
