people telling me not to do surgery

You need to ignore other people and know this is about you and your health and wellbeing. Structure yourself around positive people and ones that will provide support. 

Be careful who you tell as this is personal and is for you and you and you alone. 

Be smart and wise and know negative statements are not in your best interest. 

You will be rewarded in the end. This journey is a long one and I recommend you stick to people you trust and will support you back. 

This site is amazingly , use it to your advantage there is a lot of wisdom from all these members of this site. 

Good  luck in your journey. 

Simon.
