How do I learn to accept there's just simple things I will never have?

Because of my health I will never finish school. I'll never hold a job, own a home, or be more independent. I will forever need a caretaker, not have a back yard or walk in shower to be more independent. I can't even take my own dog out to the bathroom because of the steps and snow.

I wanted to get an educated and remote job and get off SSI. So I could get a home with a walk-in shower and a back yard so that I could let my ESA/service dog out. But staying at my parents house I realize my disabilities are just getting worse with age. I really wanted to gain my independence especially with what happened with my husband's health earlier this year. But it seems like it's just not going to happen. How do I accept this without getting depressed or hopeless?
