Guinea pig problems?

So a month from today, I will have had my guinea pig, Sprinkles, for a year. She is so cute and soft. The thing is, I don't think she likes me. Or she's scared of me. I know that guinea pigs are naturally skittish, but I've had her for almost a year now. In the beginning I really tried to warm up to her. I gave her some space for a little bit though, because it wasn't working. Everytime I feed her i pet her (if she lets me) while she's in her cage. This is the farthest I've really warmed up to her. I've held her maybe like 5 times. I don't think she likes it very much. Don't worry I've watched videos and I'm holding her correctly haha. I tried the towel method, but I can't even get her in the towel, becuase she jumps out of it while im trying to wrap her up in it every time. Today, while I did my homework, I talked to her and sat with her the whole time, hoping she would warm up to me more, but she didn't. Am I doing something wrong? I really want her to be like my best friend can you please help?? Thanks!
