Tongue cancer

Hi I had surgery 6 weeks ago now 80% of my tongue was removed and tissue from my leg used to make a flap... Have entereal tube in my stomach for feed as can only swallow small amounts of fluid for now..Voice completely changed and hard to talk something that has hit hard . Radiotherapy and chemo starting in a weeks time... I'm still in shock as my surgeon said if he hadn't have operated when he did he wouldn't have been able to as tumour was aggressive.... All so scarey
