I also don’t have the friends required to buy it with gold, and even less gems to unlock the new island(s). I already have level 5 hatchery, over 350 dragons, and 20 eggs in storage. What should I do?

Buy the dragonanarium with slots, stop breeding and hatching eggs. But more importantly get friends and gems to expand, you are going to need the room not only for dragons but for gold earning.

Only buy expansions with gold, save gems for islands. Get friends through Facebook, your alliance, or check for a topic on this forum. Collect regularly and use your meridian tower daily for extra gold.
Earn gems in league battles, videos and events. Use the jewelem tower daily. Save the gems for buying the islands. Don't waste gems on getting breedable dragons.
Earn tokens where you can and use them to upgrade your existing habitats so you can fit more dragons on them.

Do you still have the device? Have the app on the device? Did you connect it to Google within the last month or so? If not, you may have lost it for good.
