Two things that very quickly occur to me. First, in my book it is totally and utterly ok to send your child to school, or preschool, or whatever because they are high energy or whatever it is and you just need a break. I am really not a fan of the school system, but I do believe, honestly, that its fine to use it for a break. Just be honest with everyone concerned. OP not saying this is what is going on with you but I just wanted to say, don't apologise if it is, and dont apologise if that is why she was in preschool. TBH, though I am extemely pro-HE and always wanted to HE my kids, my three children have ended up going through a very, very flexible waldorf kindergarten and I have basically used this time to get some 1-1 or 1-2 time with my kids. My family did need this. Those kids with loads of energy can be really, really trying and exhausting, and sometimes, the situation is just what it is and your job as a parent is to get you all through it as gently and kindly as possible.
I think if you can't, or don't want to send your child to school, and you need a break (and, again, OP, not saying this is your situation), or you don't need as much of a break as provided by school or you don't think school would really provide a break yada yada then you need to look at other ways of getting that break. I think, for me, its really important to be realistic about my need to recharge. For a period of time after I started homeschooling my eldest I was out of the house most nights doing music stuff, mainly, or seeing friends, just because I NEEDED the time with adults and not with kids. I've adjusted now but he's also a lot easier. We all cope in different ways, the important thing, I think, is to be honest about how hard this job actually can be and realistic about your need for a break. You, or, I at least, need a break so we can care better for our kids. Its not fundamentally a selfish thing.
Second thing is, to be totally honest, if this was my child I think I'd put the ball right back in their court. I don't think I could cope long term with a situation where I had to be with one of my kids 24/7, not just around them but actively around them. (sorry if I misread this, but it sounded like whenever she is awake, at home, you need to be watching her). I think I'd need to be working with her to create a situation where I got a break too.
Total long shot but my kids do sometimes get bored and want company when they have spent a lot of time with other kids. I find that they just need to work through it, and then they are great at entertaining themselves again. But they do sometimes have a day or two, say after a camp with friends, of saying they are bored without their friends. I have to admit I am quite mean about this and while I'll work with them to find something that they could do, I won't come up with a list of ways that I can entertain them (usually. Sometimes I feel sorry for them,its not nice coming down after a holiday). I do think its really important that they learn to do this for themselves. I also, genuinely, do not think boredom is a bad thing. Unpleasant, yes, if you are not used to it, but boredom, I think, is so often a catalyst for change. Wonder if, for her, after she's had a week or two to decompress from preschool she might start entertaining herself a bit more?
If you were in the UK, which I'm guessing you are not, I'd recommend finding a local steiner/waldorf kindergarten and looking into sending her part time (ours does very generous bursaries). Or approaching a state school (public school?) and trying to negotiate part time attendance. But I don't know what the options are for you where you are. I do think that a strong, secure, basically happy family will always trump any crap the school throws your way.
