My journey toward Islam is filling me with anxiety instead of peace

Assalamu alaikum. I'm going through a really tough time right now. My family doesn't practice Islam at all-they don't pray or fast. When I was younger, I'd talk to Allah during hard moments, but I couldn't pray openly at home. This Ramadan, I finally started praying regularly and fasted the whole month. At first it felt amazing, but slowly I've become overwhelmed by paranoid thoughts, guilt, and this weird split feeling in my mind. For instance, if I recite a verse too quickly by accident, I worry, 'Allah probably thinks I rushed it, so my prayer won't be accepted.' When my hijab bothers me during salah, I stress that I moved too much and ruined it. If I have to postpone a prayer (still within its time) because of a task, I tell myself Allah will delay my blessings since I chose something else first. Missing a prayer due to illness recently made me hyper-alert-every little thing that goes wrong feels like a punishment from Allah. I used to make wudu at a certain sink, but after getting sick and vomiting there, I'm convinced it was a punishment for wasting water, so I switched spots and now obsess over water use. Sometimes during dua, intrusive thoughts pop up like, 'Astagfirullah, what if Allah isn't real? Maybe repeating prayers just tricks my mind psychologically,' followed by intense guilt and confusion. I know nobody's perfect. I'm not a bad person-I try to be kind, dress modestly, and do good-but I still feel guilty for no reason. Please don't judge me.
