I need help, im very stressed???

Okay, I am just going to let all my problems on you guys. Firstly I have been sick for a few days, secondly everyone is getting on my case since I do homeschool because I was very absent last year because I have bad acid reflux, and emetophobia, so my mom is saying I need to see a psychologist because I have a fear of going to school, which I dont. Also i have news that since I have not been going to school my dad, and stepmom have been telling my sister behind my back they think I am gay because I dont go to regular school( Which i am totally straight). Lastly my dog is very sick, she has thrown up 15 times, is not eating, has been drinking, but shes making these awful coughing up sounds, and with this economy my mom cant take her to the vet.So to sum it up, My parents think I am mental, stepmom+ dad think I am gay, my dog and i are sick, and my mom cant afford the vet, so do you guys have any advice, thanks:D
