Depression Support Group
Depression is a real and debilitating condition that is often misunderstood by family and friends. Its meaning can range from a prolonged period of sadness to an actual mental illness with specific symptoms. Find and share experiences with others who are going through the same struggles.

The other thing Depressed folks have to remember is bad days here and there are normal, every one had them whether they have a Mental Illness or not....so don't panic every time you have a bad day, sometimes its just a bad day.
As for meds to help with self-harm, there aren't many. Lithium can help with urges, but doesn't work on everyone. The way to deal with Self-harm is learning healthy coping skills to replace the bad ones, doing DBT Therapy and things of that nature. It's not easy because you have to retrain your brain on how it deals with stress and anxiety, but it's worth it to stop the self-harm.
