I just woke up in the middle of the night and really started overthinking and felt really anxious, suddenly I felt an urge to throw up and my chest started burning and I wasn’t visibly shaking but I was and still feel trembling inside, I thought I might die for a moment, really uncomfortable, could this be a mild panic attack or something

For context I have lost my parrot a week ago in a really traumatic way and since then I feel like my anxiety is getting progressively worse every day because I’m scared about my other parrot now. I haven’t been able to sleep more than 4 hours almost all week. Right now I’m lying in my bed thinking the other one is dead
