Hi and welcome to the forum.
I'd like to suggest you contact the ANA and ask them for their informational brochures and their WTT (willing to talk) list. Not everyone on this forum is on the WTT list and you may find someone in your area who would be willing to help you during your recovery if you have surgery.
Don't get me wrong, the forum is great - but the WTT list will give you some additional resources, which is important since you have a daughter to care for.
As others have said, radiation may be an option for you due to the size of your AN; don't let age be a deciding factor. It would be beneficial for you to consult with doctors who do radiation, doctors who do surgery, and doctors who do both. You need to get a well-rounded perspective of your options.
As for your questions regarding life after AN - I was 45 1/2 when I had my surgery (two years ago) and I live a life just as full as the one I had before my AN. I work the same job (accountant), I travel, I take care of my children (single parent; two teenagers), etc., etc., etc. As K mentioned, life is good
I am SSD (single-sided deaf) from my surgery, but there are far worse things in life.
If you do opt for surgery, you may need to have someone be with your daughter while you are hospitalized, and you may need a little household help for a week to ten days once you get home. Beyond that, you most likely won't need long-term care.
I didn't see any mention of where you are located, but if you give us a general idea, someone on the forum is sure to have a suggestion of a doctor or a facility where you can go for treatment - and to find help with your recovery - if that's something you want.
Feel free to ask us anything, or just lean on us when you need to; that's what we're here for.
Best,
Jan
