Do you feel i messed up and made her uncomfortable that day by giving her chocolate?

I posted here on Tuesday, how I gave my crush Anshika a Snickers chocolate. She is in my class where I started going for preparation of upcoming exams to get into an MBA B School. We are both 22 year olds. I was pretty shy that day to give her the chocolate but my friends were with me and I finally gave her the chocolate. She did smile and thanked me and we did a handshake but for the past 2 days she isn't saying me hi or anything. Usually she used to initiate convos with me or at least say me hi but she isn't even saying me hi and I am still shy to initiate any talks with her. Is she really angry on me that I gave her chocolate that day? Whats worse is i see her talking with her male friends and I feel sad. Did I really mess up? It sucks being a shy introvert honestly. I have 0 confidence to even say her a hi on my own.
