Cancelation of my cover

I am so sad and disappointed by the service I received from Discovery, first I app**** and their broker gave me a call and helped me fill in the forms. There's a section on the forms that ask about Mental Health. I did fill in stating I suffer from depression and anxiety as the main reason I am applying is to see a the****** as I was using them before at my previous company. Two days ago I received a call from one of their agents regarding the authorization code I needed to continue my session.

Apparently, they have to cancel my plan and decline to pay for my sessions as I did not disclose that on the forms however their broker advised me otherwise, and if I do appeal there's a waiting period of 12 months that I will need to wait in order to see a the****** again. I am not sure if I should tell my mental health to wait until a year. I have used them before and never had any issues for 4 years now they did not even give me alternatives they just sent a cancelation email and I should figure out the rest my self. I am disappointed and hurt to say the least.
