Only you can answer that question. But I think most of us have been where you are, Brother

It's called "The Wall."
Here's what I wrote about this a few years ago for the FAQ's. Hopefully it will help.
There should be a few more of the guys who will pipe in and share their own stories about hitting the wall, too.
Make no decisions. Take the rest of the week, and the weekend, off. This is a hard time of year ... it's been a long winter. Plenty of cold, dark days in the Garage and no apparent progress to show for it. Been there. Got so frustrated, I just wanted to torch it all. Well, read the link

Bottom line -- You're not alone. The frustration is real. We've all been there. Hang in there. But take a break. Don't flog yourself.
Pop in your favorite Great Big Sea CD (Mine is "Road Rage") and know that Spring is coming!
