where do you go, what do you do, when no one understands you

when all you want is for someone to understand you and comfort you? this is me...the only people that understand me are my elderly mum and dad, mostly my mum...i adore her and she loves me back to the stars and understands me inside out....but she is getting older now, and i worry how long i'll have my mum for?

outside of my mum and dad, i have no one, no support system, no friemds anymore...i'm all by myself and live by myself, my mum and dad live an hour and a half away from me...often times i pour my heart out online, because i find it hard to shoulder my situation by myself and 'keep it all in', like a man.

i just want someone to understand me? and help if possible? but its very difficult to find that nowadays and especially online, in my experience anyway.
