That's because of an inner conflict, no matter how big or small. Brainworms are absolutely deadly if left to writhe around, that then leads to lack of motivation and enjoyment in things you would normally like to do or experience. That battleground will always be the hardest, and that stems from people wanting to search for a purpose to life.
Funny thing is, the more you actively try to search for something like that, love, success, etc - the less likely you are to find it because you have to find the inner happiness first.
It's like having to clear a PC of viruses after dodgy files sneak in. You can do it, but it takes a lot of effort and a desire to want to overcome it - not always fully - but to the point where it feels like you can enjoy things again, even if it wasn't the same things you used to.
It takes time, but it is possible.
