I am so beyond stressed out

So this week alone I have spend about 900+. On Sunday my puppy was having some sort of reverse sneezing episode he’s had it before when he was 2 months old but I would do the rubbing neck and blowing into his face trick and it’ll go away. This time it did not it lasted so long and I’m a very panic person so I rushed to the er with him he’s vitals were normal thank god but I was very stressed out since so many animals around me were not okay even a poor woman’s cat died in her arms I was very anxious thinking the worst felt super light headed and asked if I can sit down somewhere with my pup. Then the vet assistant came with the estimated bill 700 for radiology I was just so lost in what I should do I didn’t have the money if I did it would be on a credit card. Then the vet spoke to me she told me that he’s fine and send me home with meds that it is probably kennel cough and I should just check up with his vet. The bill was about 300 and just 5 days prior I took him to the vet for his exam progression and two final shots that appointment was about 300+ as well. And then the next day I was had work as I was getting ready I was having such a huge nosebleed probably from the stressed I endured as well as dizziness and nausea and had to call off of work which sucked. So in just 5 days 600 dollars and I have pet insurance in hopes of getting something back. But nope I have exhausted my primary care allowance and they were both under mine deductible so I didn’t get anything back. Then yesterday my light goes off had to restart it so another 300. 900 in a span of days like goodness being an adult is terrible 🫩. I also go to school and I have missed about 6 classes and I do have medical depression so all this is just not good. And then today I am playing with my puppy and notice a small bump he never had… like sigh. I just feel down since I feel like a terrible dog mom because what if my puppy needed to do that 700 proceder. I have been applying to have a second job I just don’t care for school right now he is one of my sole reasons I even have the energy to get up and do anything I just want my puppy to be okay.
