Someone once asked...
Someone answered with kindness...
It's a part of being human. I'd say maybe, you spend too much time consuming things that don't feed your soul, that don't make you happy. Like doomscrolling. In my experience it won't go away quickly, you don't just go outside and feel the sun on your skin and suddenly everything is good, but, if you do it regularly, if you take care of your body and mind, you will start feeling better. You also need to try new things, even if you're not sure about it even if it's just a tiny thing like trying a new recipe. How else can you find what makes you feel good? My last word of advice would be, let go when you need to, acceptance and forgiveness is needed for inner peace.
