How to deal with disapproving family?

[dinosaurdammit]

So my nana came to visit for christmas. I thought everything would be great but from the moment she got here she downed me for EVERYTHING, mostly for my pets. I had to bring my female boa home because my friend had to come home, clean and I would be able to return athena the next morning after the fumes settled. Well we kept her in our bedroom which we always shut, somehow my husband left it open and she saw the snake. I should probably mention she hates just about everything but reptiles are at the top.

From the moment she got here she would just hawk eye my failures. I would try and try and try to please her and just fall flat on my face in a pile of horse manure. It made me feel awful. My husband was busting me too because he gets uneasy with her around as she is hyper critical down to how I parent my kid.

She started crying and making a huge fuss which got me all upset, i was shaking and crying and snot came out of my nose like a banana slug after a good rain. She basically gave me the ultimatum of "Get rid of the lizards or I wont come visit".

Now I love my nana, more than you know. This woman adopted me when no one else would and gave me a good life, although overly strict and a killjoy. She always bust me on EVERYTHING and always reminds me that I never live up to "how she tried to raise me".

I am already heartbroken about my female boa, watching her act the way she does is heartbreaking and the vet is still unsure whats going on. I tried to explain to her that reptiles make me happy and I enjoy keeping them as its so rewarding. She will have none of it. So much so she actually left. Like got up and had me take her to the airport and left. This is just- ugh- I honestly dont know what to think.

I have never had anyone give me such ultimatums and I feel it is WRONG of her to do that to me. I never go to her house and tell her how to run things and while I understand she might not like reptiles am I wrong for feeling conflicted? Has any one of you ever had to deal with family giving you grief over your hobby- you know what, reptiles are not my hobby, they are my passion. I swore to myself when I got my own house and money I would have as many as I could afford.

How do I go about telling her that while I respect that she doesnt like reptiles maybe she should reconsider trying to give me ultimatums on my pets? I suck at confrontation, I usually end up just folding like a soggy deck of cards. I mean I am an adult in my own house but maybe she is right somehow. She did raise me but at what point should she not have a say in how I live my life?
