Should I crate train?

I’ve had dogs all my life, but this is the first one that I’m personally raising and training. None of our other dogs, including our current adult dog, have ever been crate trained but I am an incredibly anxious person and wonder if it would be better for my mental well being as well as my puppy’s. Our main issue is bedtime, it’s been inconsistent and I’ve only been able to sleep for one to four hours a night so far. I’m currently writing this from my living room floor at one in the morning while she sleeps on her bed down here. She was fine sleeping in my room two of the nights she’s been here, but the other two she’s insisted on being downstairs. She wants me to be near her, and I think she might want to be near our adult dog too? She’s very fond of her. I’m just not sure what to do here. She’s too young for me to leave her alone down here without being gated in or crated but the couch is horrible to sleep on and when she does choose to sleep in my room I still barely sleep because I’m paranoid about her getting into something or somehow managing to hurt herself or her going potty on my carpets. Would crate training help? Would my older dog having free rein in the house make it harder to do it? The puppy seems to want to shadow everything she does. I also think it could help when I need to shower or do something that requires me to leave her somewhere, so far I’ve been getting my mom to “puppy sit” while I get in a quick one hour nap or jump in the shower but I know that won’t work long term.
