Feeling like I have to relearn

Just recently got an NX500 and am very thankful to be able to ride again after getting rid of a Grom. The problem is I've dropped the NX twice already for various dumb reasons. I now understand why people say learning on a Grom builds bad habits. The nx is completely different just on weight alone. I'm having difficulty managing it on slow turns and maneuvers. I realize it probably just takes practice and relearning friction zones on this one but I've been stranded on the side of the road already because I alwo could not lift the bike after falling. Tried every technique and it just wouldn't come up. Having a hard time not getting discouraged. Any tips or advice?
