Welcome to Psych Central, Blackened.
You wrote you: "go through depressive states, isolate myself socially, stop caring about most things and neglect a lot of responsibilities." And you asked if others experience this too. I'm quite certain you will find others, here on PC, who go through this as well. I don't happen to be one of them. My own level of depression remains, for the most part, pretty stable over time & I've simply taught myself to push through it no matter what (except for twice quite a few years ago now when I did try to end my life.)
Here are links to 3 articles, from Psych Central's archives, on the subject of depression plus 2 on the subject of suicide prevention:
Depression: Symptoms, Types & Treatments | Psych Central
Living with Depression: A Guide for Coping with Depressive Feelings | Psych Central
The Biggest Lesson I've Learned in Managing My Depression
How Suicidal Thoughts Can Become a Coping Mechanism
How to Survive Suicidal Thoughts
I hope you find PC to be of benefit.
