I'm pretty sure I have depression but I don't want anyone to worry.
Are you not worried about your depression yourself?
I'm pretty sure I have it. It'll be easier to handle if I keep it under control, but I can handle it myself.
If you know that you have depression, it is a bad idea to try to deal with it alone. Look for a mental health professional that can help you with your illness.
You are just discouraging me from doing so -.-
No I'm actually trying to help you cope. I have been there and so I know how it is. Therapy helped me gain my self back to the way I was before.
