Pro tip, enjoy life. You either only live it once or only remember this life for this one life and forget it when you go to the next one. If you made mistakes, so what, you have time, you're young. Life has so much more to offer you past a social media website. Go enjoy it. Heck, learn to forgive, even. Holding onto grudges stops you from enjoying life as much as you should. Live it to your best. If things seem bleak, the biggest act of defiance towards those who seek to make it even bleaker is to keep smiling throughout it all. Do what makes you happy so long as it doesn't harm others. Don't beat yourself up over small things.
