HELP! TMI

So long story short, my mother wasn’t present in my life and I don’t know how to do a lot of ‘girl things’. Which include basic care of my vagina. I’m barely learning how to trim my bush. And even that I’m scared of doing. Anyways I recently noticed that I wiped a little too hard and when I looked closer I had a bunch of little bumps at the top of my labia, one of my lips hangs out a lot more and it’s all swollen and red at the top a LOT. When I squeezed it pus came out and I’m freaking out what can I do? Do I wear a pad soaked with witch hazel or something??
