How do I ask about going to therapy?

Hi, I (F15) have been wanting to go to therapy for a while now. The reasons why aren’t important, but I can’t seem to imagine myself actually asking either of my parents about it.

For a little context, I’m not very comfortable talking to my parents about issues and what not. I find it awkward and embarrassing (as I imagine many other teens would)

So, I’m also wondering: How do I build trust and comfort when talking to my parents? How do I get over the embarrassment that I imagine? How do I prompt the topic of therapy?

Thank you so much!!
