First thing: It depends on every person.
Second thing: I'll tell you from my experience, hope it'll help a bit.
When I was Primary to Junior High School, I almost tried to kill myself due to depression. I also had anxiety disorders.
Depression is like when simple things aren't going as you wanted and you're afraid to accept them. It's like you detest your own self and want to end it. I remember I cried a lot, I felt useless, alone, nobody could understand me etc. Some times depression can make you think of commiting ******* - I tried 4 times, but I'm here now safe
- which will can leave a painful picture to your loved ones. I was afraid to face the outside world.
Anxiety disorder is like panick, I was so afraid of my subjects and exams at school which gave me anxiety. My legs were shaking all of a sudden and that trembling was going minutes later on my upper body. My stomach would ache, I couldn't eat or drink or speak sometimes. Also the idea of growing up gave me anxiety. (Stupid I know)
If I remember sth which could help more, I'll tell you! Hope I helped a bit! โบ
