Is this unfair? Very long please read?

Okay, I use to have 2 horses, 2 sugar gliders, a dog and a cat. I paid for all of these I was not spoiled just so you know. My mom was the one who bought me the cat though as a surprise due to the fact I lost my last one that I had since I was baby from cancer. She recently divorced my dad and got with this new guy. He did not like one of my horses because he could not ride him. One day i got sent to the hospital because that horse freaked out and after that was completely unrideable for me i think because I was so nervous to get on again My moms husband insisted I could not even bring him out to brush him he hated him so they made me sell him. They told me though that I could get a different horse. So I was going to buy a new one with my own money. There was a baby next door i was interested in but my mom kept saying she would call later until months went by i just gave up i got rid of my sugar gliders cuz i was not there enough to take care of them and i gave my dog to her husband because he had known her since she was a puppy and she never wanted to be with me cuz she wanted him instead so i was down to 1 horse and a cat I bought a puppy so i could have a companion on trail rides and right after that my mom tells me that she bought that baby horse i wanted i was upset but didnt say anything but she could tell when she asked i said well ya i wanted her and you knew that and you never called and she said well i wanted another horse (she had like 3) she kept making excuses why i was better off. and now she wont let me get a horse cuz she feels we dont have enough money but they are breeding one of theirs and buying another one for them that likes 6 horses for themselves. ( Also i had bred my horse in the past she ended up with twins that killed eachother inside her belly so i was even more hurt by this i lost a bunch of money for vet bills and for the breeding) and they were doing this now her husband is saying he hates cats and that they are unsanitary and he wants my cat gone (even though they bought chickens that are living in the house nasty) and now my mom "hates cats to" and is saying it must go and i can never get one again WTF After everything I have lost they wont let me get ANYTHING no hamster no cat no nothing!!
