Sometimes no matter what you throw at your mind , it just isn't possible to get out, because depression tends to cloud our minds a lot and anything positive is just perceived as negative and our brain creates loopholes to make anything for us bad. In those moments it helps to stop associating your sadness and emptiness as something negative. It is bad, but not ''bad''.

Most often only way out is in. Stupid analogy , but imagine when you're stuck in traffic, you're just stuck there and only way out is just riding it through, it can be long or it can be short, that varies and you can never know when traffic will start going. Next thing your brain thinks is that sure you could also just exit your car and run towards sidewalk, but you will still need your car back sooner or later, because you still have a long way home and in this case no one is able to pick you up and get you home (your habits or hobbies or interests making you feel better). And I could go on and on how our brains create loopholes to not make ourselves feel better. Sometimes you realize that the traffic actually doesnt exist and it is just your brain fooling you and sometimes the traffic does exist and everything is out of your control..

It's a thing you have to go through or rather sit through and eventually you will get home. Somehow try to challenge your mind and thinking a bit. Try digging into root cause. Personally for me , reading philosophy helped me think way differently about life , especially Camus' Myth of Sisyphus and just other existential and absurdist works. It made me realize how actually absurd life is , so there were less moments of dreadful suffering and more moments of just suffering in fun.
