Is there anything you can do to keep consistent with your ADHD meds? I can't keep appointments, organize or prioritize, get work or much of anything done when I forget to take my Adderall. It sucks because I want to do certain things, but I just cannot. My brain goes haywire. The Adderall also helps boost my mood. Not sure what you are taking but I wonder if getting and staying on your meds will help lift you. Adult ADHD can be more destructive when left untreated than a lot of people realize.

As for your dad -- depending on how you feel about the relationship, I would ask him to either contribute to the family (rent, food, whatever) or tell him he needs to find another place to live. It's imperative you set good boundaries for yourself.

Sorry you are struggling. It's a rough time of year, too. I hope things turn around for you real soon!!
