Well, this gonna make me feel like a dick...
But I don't believe in donating money to charity. It's often poorly managed and sometimes a straight up scam.
I often take the time to help people on Reddit that suffer from mental health issues.
I went to school for psychology and I've been able to help a lot of people gain the courage to start seeing a therapist. I have a list of people I follow up with every once in awhile to encourage their progress.
Sometimes people just want someone to talk to--and I like being there for them.
