Those who are dealing with depression/have overcome it, how long did it take to feel better?

How long did it take you to realize that you're depressed and need help? Also, did you take the help of family/friends, made lifestyle changes and all to overcome that miserable feeling or did you directly see a therapist? How long did it take you to feel better?

Have* I have overcome depression few times. It keeps coming back everytime life gets difficult. Especially when I feel like I'm stuck everywhere. Life has turned upside down. Everytime I tried to make things better it only made things worse, then I start to feel hopeless before experiencing difficulty to sleep and realizing that I'm depressed. I've cried a lot and stopped wanting to socialize, even when I did go out with my friends, I felt depressed

But after I shared how I felt and reached out to few of my close friends and made lot of lifestyle changes, watched motivational videos, read about positive things, I started feeling a little better. Being around kids also helped me feel much positive, but sadly everytime it comes back.. it's getting very difficult to overcome it.
