When it comes to talking to someone, would you want someone who fucked up the same way as you did?
You get empathy then.
Or would you prefer someone who's an expert in the field of psychology and mental health?
You get knowledge then.
I like both. I went to both before.
To each his own.
There're no rules here. I think you should talk to anyone who is keen to help. Don't limit yourself. Every little bit will help and that tiny stone you're stepping on will go a long way.
