Do depressed people ever regret having opened up to people about how they felt?

[Answered on Quora.com by "I'm nobody"]

For my case I did, I've been battling depression for 5 years now. Last year I decided to open up to my best friend of 15 years about my struggles and how depression has been eating me up these past few years. She just laughed and said how could I be depressed, according to her someone like me can't be depressed because I'm always happy and making others happy, so it's quite impossible. I tried convincing her that I was really going through depression and she just didn't believe me. She laughed it off with her boyfriend, and honestly I regretted having opened my mouth to speak. I thought it would be easier to open up to her since she's a medical doctor, but I was so disappointed, and highly regret ever opening up. Till this day I never opened up to anyone, I only talk about my struggles on Quora.com because at least on Quora I can find people I can relate with, and also no one knows me personally, so it's easier for me.
