One thing that helped me keep my courage through a break was op call the counselors office at school and leave a message. I said that I knew we were on break, but I really needed to talk to someone after the break, could they please set me up with someone. I was able to get in to see a counselor that week we got back, and it was a good thing I had left a message because I had already lost my nerve. She sat with me for a while and finally I was able to say what was bugging me.
I'm not sure how your schools system works, but if they have voice mail for the counselors, maybe you could leave her a message? If not, would writing something down help?
Good luck. I hope you are able to keep asking for the support you need.
