Do you think they will forgive me?

I'm 19 years old and I just lost three friends today because I didn't hang out with them today. I was my fault and now they are mad at me. We made plans to go and look for jobs today and I agreed. I would be the person driving because they don't have cars. My friends Craig & Kate are boyfriend and Girlfriend and Angela is a girl I really like a lot. They aren't the best of friends because at times I feel as though may be using me but other times they are really cool and fun to hang out with. The reason I didn't want to hang out today is because my acne was really bad today and I didn't tell them this but I didn't want them to see me with a bunch of acne especially the girl I like a lot. I did lie a little and I do feel bad because I really wanted to hang out with them but my acne is really bad and I'm hoping I can improve it fast. I said sorry, but what else should I do? I admit I hate when people are mad at me and I know I shouldn't worry as much but I do. Did I lose three friends?
