I would say I was in a low part of my life a couple years ago which lasted about 2 years. Not sure what the exact criteria is to call it depression. I was feeling lost and did not know how to move forward. Just knew that I didn't like where I was at. I have a lot of pride and don't like being a burden on other people so didn't talk about it to anyone. Not something I would recommend but this was the path I took. This is a personal journey and depends on your own tendencies. As I was lost I kept on trying to find ways to improve and tried them out. I made a lot of changes as there was a lot of things that needed changing and this will be specific to the person. I constantly try to understand myself and why I do certain things and try to negotiate with myself in a way that I would accept it. One thing I noticed is that I would not do what I set myself to do which could have various reasons that you need to find the reason for. It is was long journey but bit by bit I started to put things into order and I would say I am good now.

The main things that I would mention is that you have to find out what is in your control and what is not (stoic philosophy) and change what is in your control and accept those that is not. "How to be Miserable: 40 strategies you already use" was a good book that kind of ripped me apart on all the thing I actually did to make myself worse. Here are some of what is discussed in the book https://www.youtube.com/watch?v=LO1mTELoj6o. Next was to find meaning in suffering. It is masochistic to put yourself in terrible situations but some times it is important and has meaning to do so. This I got from viktor frakl's "Mans search for meaning". I like this quote from the book, "the person who has a reason to live can bear any how". Lastly, I would say to put things, into practice. I tend to be fascinated by ideas more than to actually using them which becomes an unhealthy obsession on itself.
