Anxiety being out

I'm having extreme anxiety about going out tomorrow on my own. I'll be out by myself for at least 4 hours and I'm nervous. My baby feeds every 1-2 hours. He's a week old and we haven't established bf quite yet. We're still struggling with latching. What do I do when he starts to cry on the bus for a feed. If I can barley get him to latch in the comfort of my home how will I do it on the bus. How do I burp him on the bus. I'm 18 and FTM. If I pump how do I give him the bottle without warming it up when I'm out. So much anxiety, I don't ever want to leave my house
