Hi Nemo!
I feel yer pain bro! The great news is that you have a welder, and canuse it. It's a shame you HAVE to since your plow blade broke but at least you CAN repair it yourself. That is a great thing...
Eventually this will stop and you will be able to look back at it. It's hard work and it is frustrating to have to keep removing HUGE amounts of wet snow...
I would not be able to do that.
Keep your patience and stay as calm as is possible. The sun will come up tomorrow and GOD is still in control..
Hang in there bro..
yer pal,
