what's wrong with martha in baby reindeer

Martha was a baby reindeer who was struggling to keep up with the rest of the team during training. She had been struggling with her balance and coordination, which made it difficult for her to keep up with the rest of the reindeer as they practiced takeoffs and landings. Martha was also experiencing a lot of anxiety and stress, which was affecting her ability to focus and perform during training sessions. The other reindeer were worried about Martha and wanted to help her succeed.
