I need to relax and switch off my brain...

At what point should one consider themselves a grown up?

what makes me a grown up?
Is it age?
Is it kind deeds shown towards others along the way?
Is it being a mother?
Career?
Achievements?
A settled family life?
Having some kind of status?


I need to relax!
I am in thinking mode and working myself up into a panic, I am fearful I haven't achieved anything worthwhile, I am afraid of being in my job just paying bills and never being truly satisfied with what I am doing.
I am afraid I will never contribute something positive to this world.

I think I just need to get in the bath and shut my brain down for a bit. I am thinking alot but I fear alot of what I am thinking is nonsense.
Now I fear all I think is nonsense...
I don't really like the idea of being a 'grown up anyway'
Sounds restrictive...
Is being a grown up the same as being mature?
Actually I'm not sure what I am thinking today, its all a crazy blur, whirling around my mind.
My age states I am a grown up-but I'm not sure what being a grown up means,
am I doing it right?
I guess I probably seem alot more immature than mature at times, but series of events in life has had me stepping up to the maturity mark and facing the moments at the time as a mature grown up-(I make it a practice never to stay in that position too long) ; )

oh dear...
Bath time...
Stop thinking, stop thinking...
