(Vent/advice need)(summary at the end) 
Okey so, for context my mom is a single parent and never met my dad. I am 16 and till now my mom have answer a few things if I ask, but stuff as like where and when they met or why wasn’t he around nothing to specific cause I never ask too much. The thing is my best friend knew a lot of things about my dad because her mother and my mother were friends at the time and she told me a lot of the stuff she was keeping from me, how he was a dangerous person, involve in politics, drugs stuff like that and how he probably orchestrated a robbery to my house and an almost kindnapping of my aunt. My friend told me all of this already like two years ago and I have had time to process it an all while facking ignorance with my family. Yesterday in a family dinner my grandpa for supper drunk and start to tell all of this and a bit more stuff I didn’t know about in a pretty bad way. Now my mom is worried about me cause of how I supposedly learn all of this and how it all went and so on. And she offer a visit with a psychologist so I could talk about it with someone professional. 

Here is the thing, I am really not that affected by all of these. I am used to my grandpas outburst and I already knew the most “shocking” parts for a while. But at the same time this is my chance to get in contact with a professional about my depression and other stuff my family doesn’t know about. I really don’t know if to take the offer cause I have no clue how confidentiality would work nor if it even fair to make my mom think I am affected by this enough to talk to someone, which would make her feel super guilty and worried, when it really doesn’t. I just don’t know what to do 

Summary: my grandpa had an drunk outburst and told me in a pretty bad way some truths  about my dad who I never met, which in reality I knew for a while already. My mom offer a visit to a psychologist but I don’t know if to accept or not cause I really not that affected about it but I may not get another chance to see a professional till I can afford it.
