I've been having horrible intrusive thoughts since about sixth grade, so it's been about three, almost four years now. Sometimes they're graphic, and other times it's just random insults to friends. I have this stupid fear that people can hear what I'm thinking, which just makes it worse. I have no desire to actually take action on the thoughts, they just randomly happen until I'm completely focused on suppressing them. I also tend to obsess over thinks I've said to people, sometimes for hours, worrying about whether they thought I came off as creepy, or worry if I should have said something a different way. I also get random depressive episodes, where I lose motivation to do literally anything. I have this fear that Im somehow faking it, and that for some reason I subconsciously want a mental illness. I've been having suicidal thoughts and have been self-harming lately, and I think I really need to tell my parents. I'm just scared they won't understand, or will just brush me off. I need to know that my symptoms are valid before I tell them, and I need an idea of what I have so I can get properly diagnosed. I realize a professional will most likely be able to identify the symptoms, I just want to be sure.
