I read some of these things, and I can totally relate (other than the sentiment of surviving the week just to get to the weekend...I don't even remember what it was like to have consistent weekends). I think I'm just numb at this point. Any scraps of free time are spent trying to get through the massive list of neglected house and business responsibilities. Any fleeting moments I take for myself (which are rare) are usually filled with guilt as I just run through the list of things that I should be doing or the additional work I'm putting on someone else by myself not being there. If I had two days to just do what I want, I don't even know that I would know what to do with myself. Which is probably when I feel saddest knowing I didn't used to be this way. I have been getting the occasional weekend trip here or there, and I was able to take a proper vacation last year, so it could be (and has been) worse. I'm just fully whelmed, and totally burned out, but I feel like I'm mostly keeping a good outlook on things which is at least something. I keep reminding myself that the only thing in this world I have control over is my attitude, so I try to make it a good one as much as possible.
Bad times pass, and things will always get better. 20 months ago I would get up at 6 am to go to work, work until 7pm, come home so my wife could leave to go to her work. Fix the dinner for the kids, get them in bed etc. Sleep a couple hours until the wife would get home around midnight, then I'd get up and go down to her work so I could fix all the 3d printers that were down. Then back home by 2-3 am, to sleep a couple more hours. Rinse, repeat, 7 days a week for months. My life isn't like that anymore, and every month things seem to ease just a bit. This is my year to get caught back up and hopefully regain some semblance of a life again.
