You're going to have to confront what it is that's making you feel this way. Happiness is really a state of being more so than a state of mind. And what I mean by that is when your "being" is happy you are blissful 24/7.
Long story short, been suicidal & severaly depressed a large amount of times and didn't start feeling Happy until I took time to appreciate what I love while also building up a routine of spirituality.
This exact route probably isn't going to work exactly for you but this is where actually digging into the meat of your issues falls into play.
Example: "My girl is always vocally abusing me. I should probably break up with her, cut off all contact/block her messages" <- This works but may be completely different in another situation, for someone else but the fact that they actually took out time to understand themselves, what they wanted/liked/support, & what the other party involved is doing created a state of understanding which leads to finally saying "Enough is enough, I'm tired of feeling like shit so I will cut out the bullshit & remember to try my best every single day from here on out."
Some more practical shit: Cut out low quality food, do an entertainment purge, work out, & start getting more involved in group activities. But do all that shit consistently for 3+ months.
Fixing problems is really how long can you stay making the right decisions before self sabotaging or having a mindset geared towards being a victim.
