That sounds extremely frustrating @Queenie and definitely not what you need to hear from your doctor when you are doing everything right - so rude!

I hope you begin seeing the benefits of your diet and exercise soon - I am in a similar boat as you atm - I lost a little weight but have plateaued and finding it hard to move any more - hopefully when the weather improves and I can start the beach walks again that will help - I have been predominantly walking in the pool but can only do that twice a week at the moment - hoping also to increase that to 3 times a week. 

Goodluck with it all Hon - fingers crossed you see some of the benefits soon.
