You don't want to overthink it to the point that you get stressed out and back out of the conversation, but Weichman says that mental preparation is important so you're not caught off guard. These are some situations you can prepare for:
* Guilt-tripping. Your parents might say something like, "You have the best life! You have a roof over your head/lots of friends/whatever. You shouldn't be depressed!" If they do, respond with, "Yeah, you're right. I agree. I shouldn't be feeling this way, and that's how I know I need help."
* Minimizing the situation. They might say, "All teenagers are moody sometimes. You're just having a bad day. Stress is normal!" In which case, you can respond with something like, "I understand what you're saying, but this is more than that. This is having an impact on me and my ability to live my life. I don’t know how to manage it on my own and I need help."
* Making it about them. Think, "I failed, I'm such a bad parent, I can't even raise a kid who is happy." In this case, you can say something like, “It’s not that you’re not doing enough. I’m not saying that anything in our family or my school or our environment needs to change, it’s that I need help.”
