How do I get over this huge embarrassment?

To clarify, I'm male. Here's the story, when I was at school today (I'm in 11th grade) I had an "accident" on my way to the bathroom, I defecated on myself right in front of the stall. After this, the bathroom smelled really bad and I was hidden in the stall and had no way to clean myself because there was no paper in the stall. People kept coming in and commenting about it and the stalls doors aren't exactly the best so they could see a little bit of my face and since the people here are nosy, they tried to peek in. Eventually, a family member got to the school and brought me a change of pants and I was able to leave without anyone other than 3-4 friends seeing me but they understood the situation. I'm not so embarrassed about the situation itself but the thing that gets me is how the people I know and my friends will react and especially what the girl I like will think of me. Some of my friends understand the problem and they know it could happen to anyone and it's not something you can control but I'm not so sure if the others aren't as shallow as to not criticize about it. I'm really emotionally puzzled about this. I don't mind those other people's comments because honestly, if we took every comment to heart, we wouldn't be able to live but as I said before, I'm worried what the girl I like will think of me if she finds out which I'm not sure she has...yet. I haven't had many embarrassing situations happen to me and I'm not really one to comment on others situations. Can anyone help me deal with this or give me any advice to get through this? Although, I'm mentally strong enough to not consider something as drastic as "suicide" or anything, right now my self esteem is in shambles and I really don't think I can take any more comments or insults.
