Me being a Cheerleader once :'(

I was in cheerleading, but now I'm not. I really really love cheerleading. I quit because I missed 2 practices and I let my team down, so I decided if I wasn't there, they wouldn't be that mad and stuff.. Turns out, it makes things worse, and so I felt worse. Now, most of the cheerleaders that see me in the hallway just ignore me :'( I told one of the cheerleaders I'm going back at October, but now I can't, because I hurt my knee and I can't do too much jumps and stuff, my doctor suggest me not to go back :'( I really love cheerleading and I really want to be a part of them. :( :( :( :( :( :( :(
