Mist, in all seriousness, you're accustomed to being around people who either don't care about your life or happiness, or actively obstruct your life or happiness. If you've never been around someone who genuinely wants you to be happy and helps you and works towards that goal, then you need to find that. There's not any particular one activity you need to be doing to "be happy", happiness is a frame of mind and a peace with life and yourself knowing that things are working for you now. If you meet someone or make some friends that are genuine good people, and cut the bad people out of your life (this is necessary), your happiness will go up without any change in activities whatsoever. Now, you'll probably find that you do more activities or are able to better pursue your hobbies or whatever interests you once you reach a better state of mind, but those things will happen organically. Cutting negative influences from your life is a critical component of finding inner peace and moving forward through fucked up shit in life.
