I think there's something wrong with my brain
Can you tell me more about why you think there is something wrong with you?
I have emotional changes at times, for instance when depressed I have thoughts about hurting myself.
The first step in recovery is admitting that you need help. If you are thinking about hurting yourself, you should seek therapy before you do something dangerous.
Don't be mean and judgmental.
I am sorry, I am trying to help. I do not judge you for you thoughts, I only want you to seek help.
