The point is what you make it. I struggle to find that myself, but I believe it is possible to GIVE your life purpose. Maybe it's caring for another, maybe it's finally writing a novel, learning an instrument you've always wanted to learn, taking dance lessons, reading the books you always meant to read, raising your children. Maybe it's just watching as many sunsets as you can and enjoying their beauty. Maybe it's watching every episode of Days of Our Lives twice. It doesn't matter what others think of your purpose as much as it matters whether you feel satisfied or fulfilled by it. And purposes can change as time goes on.
I of course understand that our mental and physical health doesn't always support what we want to do. For some it never does. And part of why I am here is that I believe that it is absolutely your right to do what you want with your own body, and that no one understands what you're going through better than you. If you decide that living is worse than dying, it isn't my place to say your reasons are invalid. But for myself I go from feeling like all is pointless and I have no future, no hope, and no chance of happiness to thinking life is beautiful and fun. Helping people and non-human animals is often the greatest joy in my life, and when I see an opportunity to help someone I take that as my temporary purpose, be they a hitchiker that needs a ride or someone in line at a grocery store that's a little short of money. Today this website has given me some purpose. If I can contribute to a community and offer help and/or comfort to those in pain, well, that's something at least.
Much love. I have plenty of days where I wouldn't have the positivity in me to type what I just typed above, but luckily today isn't one of those days.
