I also suffer from depression and anxiety. I have since I was 15 years old. I believe in runs in my family. I've only sought professional treatment for this in the past several years. I see a psychiatrist and I take some medications. It has been difficult. It still is difficult, but I'm doing pretty well.
I recommend that you seek out a psychiatrist. A lot of people don't understand that chronic depression and anxiety are real ailments. They will tell you things like "you're fine, it's just in your head!" Don't listen to these people. They mean well but they are ignorant. Get the help you need.
Feel free to message me.
Good luck to you!
