Hi, I too feel that you should only share what you are comfortable sharing. After all, therapy is about yourself and it's very personal, which is something even our parents should respect. I do not share a close relationship with mine (in fact they caused most of my current issues) so I will never be ready to discuss my problems with them. They only know about my suicidal ideation because my school contacted them, and that was extremely awkward and uncomfortable.

I know you stated that you do not wish to lie to your parents, but perhaps if your distress at sharing this info overrides your wish to be honest, you could see your school counsellor first (I am assuming you are still studying). That way, your parents would not be suspicious of your whereabouts and you can simply avoid the topic, thereby still remaining truthful. If you have to share, then maybe printing out your speech and passing it to them could help a little?
