Low-functioning anxiety

I’m prone to LFA, otherwise, my anxiety remains high functioning. For the last 3 weeks, I havent been able to stomach food, I fell sick and I’m not able to stomach medication making my recovery time much slower. I’m taking care of my sick cat all the while juggling with a full time corporate job and it’s been really frustrating. I’m always nauseous, I feel alone. This is such a big responsibility taking care of a helpless soul and trying to attend to a full time corporate job. I’m terrified every single day and I feel like my mind’s going to explode.
