be open and honest and stop feeling shame about my situation surrounding mental health

I suffered a major and severe mental breakdown about 4 years ago and have relapsed in recent weeks, probably due to stress at work. Through the dedication of my partner, family and the community mental health team, I am already on the road to recovery. I have told the colleagues I worked with about my breakdown and they were all incredibly supportive. I hope to return to work soon. However I think I need to admit to myself that it is okay to have mental health problems. Unfortunately I hide this too well sometimes even to myself.
