You have a good attitude on trying to make the best of the situation.
We also bought with Max (HGVC though) and have had to learn a lot since then. The #1 thing is that you
do not give up on what you bought and be kind to yourself! You CAN use what you bought, it will take a huge learning curve and a lot of time to learn it. Commit the time and you can be successful. Every week, go to the booking page and play around with properties and settings. You will get a sense of what goes quickest, what seems to have lots of availability, and when there is a sale. We did stay at Powhattan (is that where you bought?) for 4000 points for 7 nights in a 2 bedroom during Thanksgiving week last year. It was a very enjoyable stay. It is the only HVC property we have visited, so I cannot speak to others. There is a possibility that Bluegreen may eventually be added to the mix (Hilton bought it, but if it goes into the Max pool is yet to be seen) and if so that would open more properties for you. You do not pay any booking fees with Max, so this can also allow you to have more frequent, but shorter getaways (long weekends perhaps) without accumulating booking fees. Booking 2-3 night stays may help you find booking holes that open up some options. There are also cash prices for last minute on both Hilton and RCI, which can help you extend what you bought.
You will have to have a mental reset on how you book travel. First comes accommodations, then if you get the reservation you want you go from there. You need to book early (6-12 months depending on what you are looking to do) or wait until the last minute and be accepting of a studio accommodation for a few days and just go explore the area and see what you see.
I hope this helps you feel encouraged. It will be okay and you will take nice vacations, just be very eagle eyed on when points expire and be sure to save any from this year you don't think you will use before the year expires. Also, use your bonus points from the purchase to splurge on a HGVC vacation at a really nice resort next year. You have two years to use the bonus points and those will allow you to stay at some very nice locations. Maybe you could get a few visits to NYC or go down to Orlando/Florida or the SC properties at the beach. Just stick to it and you can be successful!
