Hi,
I think it's normal for you to do that. If I were you, I'd probably do the same thing to my therapist. Sometimes we feel like no one understands us and if we tell them about what we feel, it won't change anything and we get tired just by talking about it. That's the reason why we choose to keep it to ourselves cause we worried that our therapist or anyone would give up on us too if we keep telling them about the same thing that we're feeling.
But it's not a good thing to conceal everything and keep it to ourselves too. We have to keep trying in making ourselves get better.
