Broken foot thru duration of preg

I broke my foot in June right before conception and have had two surgeries one before and one while pregnant. But it's still broke and Now I'm in a cast until after baby boy comes awaiting bone graft surgery. I am having a hard time with my immobility being pregnant and my older son. I can't work and I feel like all I can do is sit around. I loved my first pregnancy but I'm depressed with this one. I'm nervous to have the c-sect an my ability to heal and take care of baby at home given my condition.
