I've been suffering from severe depression for at least 8 years.
What is it like to live with that depression?
It's terrible, I feel alone and isolated.
It sounds like you have been struggling with depression for many years. It's important to talk with someone and get some help. This will help you improve your life and feel like you can enjoy it again.
I try to ignore it but it doesn't go away.
You've seen that your approach is not making your depression abate. You should talk to a professional who can help you work through your depression and perhaps help you find a medication to help as well.
