I have struggled with depression since I was 13 but I was diagnosed when I was 18 (year 12 was incredibly rough).
Every day I have lived since I was 13, my life has been about survival. That's not an exaggeration, nothing in my life gives me true pleasure. I never truly get a break from anything, even my hobbies and interests make me sad sometimes. This is going to sound ridiculous but in one my games, there is a mechanic where you can make your main characters get married and have kids. That legitimately makes me depressed and this is a game I love playing.
I have been diagnosed with persistent depressive disorder so it never goes away. It's always there and means I never truly enjoy anything. Along with my aforementioned problems, life is hell. Again, not an exaggeration.
I am trying to improve my life, I have done everything conceivable and stuff I can realistically do. Nothing has changed. If I say I think I am doomed to die alone then I think based on my life experiences, it is totally justified.
