Anxiety from the thought of giving birth


So today I found out today I’m 3 cm dilated and 90% effaced , well they sent me home because I’m only 36 weeks and 4 days. He dropped within two hours noticeably and now I’m just having anxiety what my body is going to feel like if my water breaks I’m a FTM . I was fine a couple days ago and had the mindset that I was ready but after I found out all this stuff, I started feeling weird and just full of anxiety, I’m scared to pee because he would always headbutt my cervix before but now I’m just scared my waters going to just break and I won’t know how to react. Anyone else feel that way or felt that way
