While there's no guarantee that medication will work, you should at least continue taking it, or find some form of medication that works for you in some way. No pill is going to simply give you happiness, real or "fake," but hopefully it'll alter how your brain reacts to things.
There's no such thing as "pseudo-happiness." The entire idea implies that everyone who isn't completely emotionally fulfilled are lying to themselves about having positive feelings, which is a ridiculous concept. You don't have to fear a change in yourself coming from an outside source, even pharmaceutical, because it's just another way to guide what's inside. The only difference is the shape it comes in and how it enters your head.
Happiness is complete fulfillment. There's nothing wrong with pursuing it, but the journey of life is full of hardships and setbacks as much as happy moments. Everyone lives through some form of conflict; nobody is truly fulfilled in life. Really, what most colours our lives are the small and fleeting pleasures, both day-to-day comforts and one-time experiences, and the pains of life only make them sweeter.
Even if you can't find enjoyment in those things now, maybe with a combination of pharmaceutical and psychological help, things may begin to change for the better down the line, as your mind evolves both physically (through chemical alterations) and psychologically (through changes in your philosophy). I hope this gives you at least a small feeling of hope, and I encourage you to keep going as much as you possibly can, and don't be afraid of help.
Wish you all the best, man :)
