This happened to my parents in the 90s in Florida. They did a consultation with a lawyer and he told them to stop paying rent. So they did. Saved the money and used it to make a downpayment on their first house. I don’t know if it still applies but it’s probably worth a look.
Years from now you’ll remember the good times and the shitty days won’t be rembered often. Kids idolize their parents whether we’re worthy or not. My house is a mess too. We are all just getting by some days. Don’t beat yourself up. Try to make tomorrow a little better.
