Great to hear that you are doing better and are generally a lot happier.
I would advise though that you dont just 'live with it' but do not try to get to the root of the problem that causes the dark days. They will keep coming back until you are able to manage to confront them.
I managed it myself without talking to others*, but am now happy to admit and talk to people about what I went through if asked. Depression effects us and those around us differently, and is nothing to be ashamed or embarrassed about any longer - society is finally accepting mental heath issues affect a very high % of people and we are not all "nuts" as a result
*Stupidly or stubbornly I decided that as I got myself into the mess I was in I would get myself out. But until I realised I had a problem I was making some seriously bad calls, and I lost some good friends as a result of my behaviour which I probably would not have done had I seeked help sooner
