Life - Am I Lost Or What

I used to think that if I kept plodding away that somehow someday things would get better or easier. I don't think that anymore, as I think about everything going on in my life I get very overwhelmed and just don't know what to do about them. I do try to keep a smile on my face and make jokes whenever I can but somedays I just get withdrawn and moody as I brood over things. I wonder if it is too late for me to run away and join the circus?
