<human>: Hi Reddit, I am not sure if this is the right place, but I need help.

I'm a 19 year old currently working full time over the summer and going to college during the school year. 

I love my parents. They are the most selfless, nicest and hardworking human beings I know. They came to America for the sole purpose of building a better future for their kids and their children's kids.

Everything was fine until a few years ago when my father decided to buy a small business. As a result of the business, my parents got into significant debt and had to take out several loans all of it to totaling to over hundreds and thousands of dollars. Despite this, my parents pressed on and were able to almost pay it off by working and eventually, selling off the business. However, as a result of the recent sale of the business, my parents now have to pay off a sales tax of around $90,000 in the next 3 months. This on top of me and my twin sisters student loans, and previous debt is causing my Dad an immense amount of stress and I am worried. 

What should I do? What can I do? I think my father is getting depressed and it hurts me so much to see him like this. My dad doesn't know I know so I can't really talk to him about it yet, only my Mom and my older brother. I am willing to help pay, but I know my parents would not let me give my own money. Hopefully, I'll be able to convince my Mom soon. I really don't want my Dad working till he's 70.

Reddit, please I just need some advice.

Can you give me the gist of the text in a nutshell?
