I think I have hemorrhoids?

When I go to the bathroom my poop has to come out in chunks because I guess the pain is so bad. When it comes out, I feel like it's stretching a lot and I think that's what started it. It's been like this for the past two days. Please tell me this goes away soon! I'm so embarrassed I don't want to go to the doctor for it. I wouldn't even know how to apply ointment, I never touched my anus before in my life, let alone stick a finger in it. That's an exit door only. Help!
