My Timed Entry of my current feelings

I am not feeling well at ALL. I have had many mental problems that I was diagnosed with for a while now. I guess you could say I had hope that things would have settled since then. But aside from that, I do have something on my mind right now. My dog, Coco is my best friend and I love her so much. I feel like she is the only one who is truly there for me in the family. I have never really fit in with my family it seems. Coco is still really young and very healthy, but recently she has torn a muscle in one of her legs because the way she runs so aggressively. It is not that severe at all, she doesn't need surgery, but we obviously had to be more careful with her. So instead of letting her run crazily in the backyard and hurt herself more, we walked her on the leash so she could walk and not strain anything. We also made a few more changes to our house so she didn't have to jump up to get onto her bed(s), she has many, including the families' beds if she chooses. She finally healed after about a month or so and she was getting around fine. But now, again she has started to limp really badly because of the same leg. She also tends to lift it up and not put pressure on it when she doesn't have to. It makes me so sad to see her in this much pain. However, my dad, who I have never gotten along with seems to enjoy playing the blame game. He keeps saying "you don't have the right to feel bad" "it's your fault." "YOU'RE the reason she is like this." "You're the reason she's hurting again." "It's your fault because you let her jump on your bed and she probably strained her leg again because of that." Like WHAT. I am not going to say my exact age for privacy concerns, but I'm only a teen. Some even still consider me a CHILD. Who tells their child that? Ever??? I understand my dad loves to blame things on me all the time, but I just can't stand the fact that he did it this time because I would never want to hurt Coco. I hate the sight of her being so hurt and it makes me so devastated that he's just blaming on me. I truly just wish my dad would realize how immature he is being. I really don't believe this is my fault. He just tends to say things and blame others to feel better about himself. But it honestly just hurts the most because it is about Coco, who I wouldn't give up for the world. Even more, he knows I struggle with many mental health issues and that I will 100% overthink what he is saying and internalize it. I feel as if he does this stuff on PURPOSE sometimes to see me struggle. He is like the #1 reason why I am in therapy. He has always messed up my life, but I feel as if this is the straw that broke the camel's back. I hate him and I wish he wouldn't blame my dogs' pain on me when I already feel shitty enough.
