How to do approach a friend who...

Has somewhat of a dark mind? Back then I used to let some of what they said get into my head, and it's been about a year since I last spoke to her. I want to be her friend or at least start talking to her but I'm afraid of what she might say. Any advice?

One thing about being friends and talking to someone who has a somewhat "dark mind" means that you have to be strong yourself, and have the heart and will to not breakdown and get pulled into her thoughts too. About approaching her again... Their reaction is a bit of a gamble, I'd say? It really depends on the person and the situation they're currently in. But, the best way to start talking again I suppose is to just explain your disappearance and be honest about it. But, as I've said... Their reactions depends.

You have to be willing to talk on their level. It means getting out of your comfort zone and associating with what they say. Trying to be agreeable even if you don't necessarily agree but be supportive. Some people are difficult to approach but, "if" they are approachable, they're most comfortable doing so, talking about things in the way they want to. You'll need to be a bit courageous. Be able to not let anything they say get to you. Try and see things from their perspective, even if it seems unfair or strange to your perspective.
