Best advice I can give to being happy is know your goals in life, exercise a little bit each day, do a bit of meditation for reflection helping to connect to your inner self. I enjoy a bit of writing and singing. Talking to friends and family can help half the problem, never binge or do anything to excess and confront things when they get on top of you never bottle yourself up also consult your medical professionals if things get really tough they can sometimes guide you in the right direction. The thing that helped me through in the end was having a purpose which I have found that with my baby girl she makes me smile and reminds me that life is worth fighting for regardless on how bad i feel. I honestly had no direction before kept hitting a dead end when I was younger I was enthusiastic and hopeful studying hard hoping I would achieve something in LIFE find the job and partner of my dreams but life after university hit me hard I was unemployed for 6 years which made me feel depressed and became mentally unwell the thought of feeling the failure never having nothing to show at the end of it sent me down a dark spirall My wounds are now finally healing keep reminding myself i'm no failure and a fighter and now I'm feeling a bit more at peace with my self.
