I can't do this anymore

I seriously cannot be pregnant anymore. I'm getting literally no sleep. I'm suffering from reflux, bloating and I just can't get comfortable no matter how I lay, I have tried being elevated and it doesn't work either. I just want this to be over. ): I'm 37 weeks and it's just dragging on. I'm not excited about giving birth because I'm petrified of being a mum cause I feel like I won't be able to do it right ):
