It can be safe to have friends here... but since you're a newbie I suggest you wait until you've chatted with and read a member's profile and posts for a while. Remember this is a mental health support site and there are some members who can be toxic to other members...not everyone gets along with everyone else. It isn't anything to fear because you can unfriend someone, block their posts etc if you find their posts upset you...but it's easier to be choosier about making friends.
