That was really hard to read. Losing your dad is one hell of a gut punch, now to see your family's farm go away.
It's a hard pill to swallow, but in the end it may turn out to be the right thing. I've seen more than a few cases where a farmer just keeps on keeping on under a mountain of debt from buying out the previous generation/siblings, hoping one day to finally get out from under the debt. Some do, but for many they work their lives away, missing out on their families, and are left with a broken body at the end and still a pile of debt.
Don't be afraid of a life beyond the farm. Someone of your skillset has a world of opportunities in front of them, many of which won't keep you constantly working and will let you spend time with family.
Wishing you and your family strength going forward and good luck in whatever you decide to do.
