Yes another horse would definitely help! If you can't afford a full size one get a mini. And did you say she sleeps in the round pen? I would stop having her sleep in there. She's probably thinking now it's a place to relax and not work.
And no harm in riding in the summer. I'm in MO so even though the temps are usually high 90s or low 100s, the feel like temps and the humidity are aweful. I still try to get a few rides in though so my horses don't think they get to be total free loaders, and so they don't get bored of ground work. It won't hurt you or her to get a little hot, just make sure you're both hydrated
My vet had recommended turning her out at night to get exercise. But I have heard that where a horse sleeps and works shouldn't be the same place. Plus its been storming at night so I don't think I will be leaving her out over night anymore. Thanks again for everything. I'll make some of the changes everyone suggested and update if anything changes.
