Is there something wrong?

It's a question I encounter frequently these days both from others and from my own inner voice. Of course, there is something wrong, but how can that be said to somebody else? How can it be said without revealing what is wrong, the what is I do not really know. Yes, I am tired of the trials and tribulations. My brothers are both idiots and I am not sure my sister is much higher up the scale. Sure, that is just my opinion and it's probably too harsh. Sure, I am sure most people think I am an idiot as well. I am just tired of the oldest's drama - he's now married and so in love, yet he still job hops and his kids are drug addicts and liars. He blames his ex-wife, but that is just convenient as he gets no blame. Nobody mentions his excessive drinking? Excessive drug use? Changing jobs often and blowing money at a record pace and let's not gloss over the constant whining and taking mom's money - playing on her feelings. I thought the oldest was supposed to lead? The other brother has returned to the bottle and making horrible decisions. Do I have to bail him out again, be the strong one again, be the wise/smart one again? The sister is knee deep in alcohol and drugs as well, but of course nobody is supposed to know. That's a hard answer to deliver without sparking more and more questions. On a more personal note, something is wrong - something has changed with regards to work, career, calling and I cannot put my finger on it. Yes, I never loved my job, but now it seems pointless and I've pulled back and now go through the motions - committing to nothing. What is my next move?
