That's the attitude Katie, however there are proactive things you can do before, during and after treatment with the help of a Speech and Language Pathologist that will help in recovering and QoL issues. The earlier you start the better your chances are. JenSLP on the forums is a OC survivor and notable Speech pathologist who works with patients going through treatments. Her and I speak together on the subject and I trust she will be of help.

I would enjoy all of the foods you love between now and treatment, I didn't do enough of that myself and over 90% of my nutrition is via a liquid diet. It's not all about "bulking up" though as the weight typically lost during treatment and due to stress is lean muscle mass and not adipose tissue (fat). Consider this when going through treatment as 20% of "all" cancer patients die of malnutrition, not cancer or the treatment of.

Keep your chin up and do get that second opinion, it's just prudence. The best advice anyone can ever give you is to seek the absolute finest medical opinion available to you, and MSK is one of the finest in the country.
