Personally, I think you shouldn't be asking anyone but yourself. If you need help, and need professional help, then go and find someone who can help you with your depression.
I have DID, been dealing with it for a couple of years now, and I recently made the decision to go and see someone about it because it felt like it was getting worse.
So in my opinion, yes, but it's really all up to you. Drugs help...for so long. Sometimes they make things worse. I'm not taking pills.
