Hi Harmony,
Yes, the distance symbol was the hardest for me to learn. It's so complex, I'll bet that's true for most everyone.
As for doubts? I found the best way was just to keep doing it in spite of the doubts. Eventually, you'll build your confidence.
One of the techniques I tried was to send distance healing to myself. When I could feel it that way, it helped me to know it was actually working.
Rock On!
Roxy
