I have pets who are wonderful too. The thing is I'm allergic to anything with fur or feathers. So I have 2 ball pythons.
I got the first one when she was just a tiny hatchling and I hadn't been diagnosed yet. In fact, some of my trauma was yet to come. When I lived alone just me and her, she was always wiggling at her cage door begging for me to take her out. Made me feel loved when I was alone in the world. When I have gotten sick, she's slept in her bag on my stomach and insisted that she be allowed to place her head in my hand as her pillow.
When I lived alone, I would wake up screaming from nightmares, and she would be sitting ready at the door of her cage, waiting for me to take her out and give me some different energy to tap into. Once, shortly after a family member that I was very close to was murdered (by another family member) she was playing at the head of my bed. I sat on the end, and started crying.
She was only a very small baby, but she crawled all the way from the pillows to where I was, up into my lap, and stretched herself up to my face and started licking my cheeks. That was so cute that I stopped crying for a minute and smiled. As soon as I did that, she seemed to sense that I felt better, and went back up to the head of the bed to explore under the pillows again.
I'm sorry if anyone is afraid of snakes, I know that's a common fear. My two girls have been my source of comfort when there was no person in the world who would offer me that.
