You did a great job with English, I could easily understand what you are saying.
In my opinion, depression has a hidden "claw" which directs and skews our views to see only the dark or sad things in our life. Not that there aren't dark or sad things, but they are ALL we can see when seriously depressed, and nothing outside of that. It's like we are now wearing blinders to block our view of the good things.
I have felt like you do, so understand what you are saying. Even though it is difficult to see now, the pain of family outbursts and relationship problems do fade with time. Please talk with your psychologist about feeling so overwhelmed by it all now, and keep posting here for support as you work through this.
