You'll be okay.
As a sufferer of severe anxiety and depression, I just want everyone to know what I've learnt through personal experience:
Life is beautiful, it's precious, valuable and it's very taken for granted. It's true that our lives may suck, but we need to get up and realise that there's a brighter side to life. There's always something or someone worth living for, even if we haven't found it/them yet.
We need to believe that everyone deserves to be happy. We can all reach happiness, but it's something we need to earn.
I understand that some people might find this offensive, but just putting it out there: this isn't directed at everyone.
