Depressed or stressed?

I don’t know what’s gotten into me. I’ve never had any history of depression so I’m not exactly sure what it’s like. But I’m feeling so low, I have hardly any energy anymore or ambition. My patience is at an all time low. I’m extremely irritable all the time. I used to enjoy cooking, it was the one thing I looked forward to at the end of the day was making a nice meal for my family. I have not cooked in weeks and I have no desire to. It’s starting to bug me 🥺 I haven’t felt like cooking because my appetite is also completely gone. I feel like I have nothing to be depressed about so how can I be depressed? Someone please give me some words of encouragement..
