Lance Franklin’s fiancee Jesinta Campbell has thanked the public for their support, saying they have been dealing with the AFL superstar’s mental health issue for some time.

Franklin is on indefinite leave as Sydney head into the AFL finals with his problem made public on Monday.

“I would like to thank everyone for the support both Bud and I have received over the past few days,” said Campbell in an Instagram post.

“This is an extremely challenging time for us and has been for some time now, however it has been made easier by the love, understanding and support we have been given.

“Thinking of the many others who also live with this every day and are not as fortunate to have the support we do. I am incredibly proud of Bud’s strength and courage, this has not been an easy journey.

“I am thankful for the support of the Sydney Swans, both of our families, friends and (our manager) Sharon (Finnigan).

“We are not alone in this. My heart is with my man. The only thing I ask is that everyone respect our privacy at this time.”
