I know nothing about healer but I could at least be a DPS for you to test your healing on or practice tanking while you practice healing. We can try to run with a dedicated group so you don’t have to worry about randoms being in your party. 
If you do decide to join again, and are wanting to start on an NA server, definitely recommend trying to start in Aether/Faerie but if you can’t, we can server travel.
