Hi there - I was a year older when I was diagnosed (my kids are much older though as I had them when I was quite young) - same situation, non smoker, non drinker, and a vegetarian/vegan. I had one node involved and the same surgery so I know what you are going through. It takes time. You will heal and you will be fine. You need to be patient.

Are they sending you for radiation? If they suggest it (they probably should because of the node) as scary it is, don't be deterred by this, OC is a devil you do not want to have to dance with again. Even with rads and chemo there are no guarantees, but this cancer can be sneaky and it's recurrence rate is relatively high, so if you can hit it with both barrels now and hopefully the 3 or 4 months of your life it occupies - will be it.

Hugs and feel better.
