YouTube & Mental Health
I think YouTube can be a fantastic platform to discuss Mental Health, however I feel you have to be a bit careful about what exactly you watch - making sure it is safe for you and you are receiving appropriate treatment if you need it. Here are a list of YouTuber's and their videos in which they discuss Mental Health. They can be really beneficial in letting you know that you are not alone.

Let me know who you have found helpful! I really liked John Green's video on OCD - very useful.
