Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I've wizened up since I left Smogon and I probably will still hardly use it given I don't really care about normal comp Pokemon anymore (though comp Clover is based and redpilled). I prefer the kongs and other stuff and I miss Google+ dearly.
There is no point in actively being toxic against other people or constantly complaining about life, you need to enjoy life for what it is and try not to let your anger or sadness get the better of you. There is always a light in the dark cave just for you to find. Knowledge is power and using it well will get you far in life but mind isn't what should carry you through it either, you must learn to love and care for yourself and keep yourself healthy so a balance of knowledge and physical health will help you get through life.
