Selling My Ball Python? </3

[SnowShredder]

So I bought my first ever pet (ball python) on July 1st, at PetCo. I was very happy that day and my mom was okay with me keeping it, she actually started liking it until she thought it was getting bored and not wanting to live with us. My mom keeps asking me what the hell is the snake gonna do for me and what I am going to get out of it.. this is ridiculous . I LOVE snakes, I have been handling them since I was 6 or 7 years old. She wants to take my snake back to PetCo. But I honestly do not trust PetCo, I have seen many videos on pet store cruelties and it makes me really sad . We have a 15 day refund for the snake or something like that. Ugh I really love this snake A LOT. I have cried so many times today </3. Idk what they might do to my snake if my mom takes it to PetCo. Plus, idk what to do with the aquarium and decor and all of that.. she doesn't want me to get another snake anymore. This is the worst day of my life I don't want my snake to leave </3. Btw I already made a thread like this but I think it got deleted. But yeah guys, I want to sell my ball python online a long with my stuff that I used for my snake. But the bad thing is, idk how to sell things online. Ugh I don't even know if my snake will live longer if my mom takes it back to PetCo. If we can't take it back to Petco, she will take my snake and throw it outside, she says outdoors is better for it but I honestly think my snake will die and get killed by people since I live in crappy apartments. Ugh WORST DAY OF MY LIFE </3.

Outdoors will most likely be a death sentence, please explain to her that if it MUST go, the best option is to rehome and not release. I would personally sell the snake and the equipment to someone else and not return it to petco.
Is her only reason to get rid of it because she feels it is bored? They're very happy to live in their little homes.
You live with your parents and under their roof what they say goes, but this is a little ridiculous since she had agreed with it in the first place. I see no reason to get rid of it if you are taking proper care of it
