Hi there 2 Double 0,
The position you're in right now is a very difficult one, I know, I've been there. But you're also in the best position right now to address whatever you suspect your issues might be. I totally understand the fear of looking weak, the fear of making a big deal out of nothing and the extreme difficulty in opening up to anyone. Seriously, I walked into the GP with the full intention of saying I strongly suspected I may be clinically depressed. What I ended up saying was more like "Yeah, I'm fine! Nice to meet you, bye!" Of course they were confused and pressed me a bit more, but I guess you were more convincing, haha!
I don't want to sound alarming, but it really is for the best if you can sort this stuff out asap. If you ignore it, deny it, just put on a brave face and smile there's a possibility that things will just get worse, and you'll still be unable to bring yourself to open up and ask for help because you've already invested so much energy in hiding it. This is the predicament I've been in recently, so please, please, have another chat with the counsellor or as Katy suggested write down what you're feeling (or even literally a screenshot of your post here) and show it to the counsellor.
All the best,
