I think in your case, something like a small bird, budgie, or cockatiel would do nicely. Any of the sort you may want to cuddle, hug, pet, etc, I don't think would be suitable for your lifestyle. A pair of guinea pigs perhaps, not exactly rodents, a bit like rabbits..
Just looking for some little animal to care for and keep you company, some invertebrate tank animal(s)
Hermit crabs, land snails, Even spiders, doesn't have to be a big tarantula, the little jumping spiders are great little pets, even house spiders.
What ever animals you choose, I do suggest reading about keeping them so you know how to properly care for them and what to expect from any.
There are online keeping forums about all of these, a great place to read about particular animals.
