So sorry to hear that. My dad lost his job when I was in high school in the same year that both my sister and grandma fell ill and he was supporting both of them. Unemployment benefits can definitely get you through until he finds a new job.
Also don't worry about this interfering with your dream to be a lawyer! I worked part-time during the school year and full-time over the summers throughout university to pay for tuition, and I'm now in my second year of med school and still debt free! Make sure you apply for all of the bursaries and scholarships you're eligible for. I know paying for school in the US is much harder than in other places, but in Canada you also get grants in addition to loans if you're from a low-income family so maybe there's something like this in the US too. Research all your options!
