I sympathise. I hated that age and found it a real slog... yes they're cute, but they're heavy to lug around, they don't want to sleep, they make a mess just looking at a room, everything is a drama, the tears... no thank you.
1-2 was hardest for me. It also coincided with Covid, so that probably didn't help. There was a big improvement around 2.5 when speech was much clearer and more conversational (this might be earlier for you, mine was a bit late talking). The biggest improvement for me was around 3.5, when he was reasonably reliably toilet trained, followed instructions fairly well, and generally became a bit more biddable, more fun, and easier to get along with. Also you can start to leave them in a room in their own to play without worrying so much.
Can you get any time alone? I'm very much an introvert and found being around my child all the time incredibly draining. I'm sure this makes me a terrible mother in some people's eyes, but it's the truth. At that age I used to take myself off for a four hour bike ride some weekends - utter bliss, and my partner was more than capable of coping without me. At around 2.5 I started having the odd night away in a hotel on my own.
ETA - mine is now 5 and I actively enjoy spending time with him. He's a lovely human! Still hard work sometimes, but fun to be around.
