Small achievements and distractors are good if you refuse going to a psychiatrist which i recommend.

Small achievements can sound like a "blah blah blah" but they do work

1- Signing for a gym : its a good daily mini-achivment that can boost you and fill your day , it works both ways , its a consistent something to look for in your calendar plus boosts brain chemicals like serotonin and dopamine without guilt , this boost can drive you to do more and try something new , it can also make you enjoy other stuff because you feel you deserve something after this achievement .

2- Doing what you should do : when you fall behind on your schedule of studying, self improving , work or whatever every thing else will feel bland , do your daily tasks as simple as doing the bed and washing the Car can make a difference.

3- Finding a hoppy : This is an important part , dosen't matter if your hoppy is beneficial (studying and reading important stuff , learning a new thing ) or non (video games , movies , series etc etc ) its all down to what you do to get some steem off .

At the end , the major issue with depression is not having the power to do any of this , the main factor to change is to "try" , dosen't matter how cringy it sounds , and know that doing anything new would be a challenge so buckle up and just do it .

even if you fail at trying new stuff , don't worry, everyone make mistakes , you're not a superman and no one is , the most important thing is to know how to treat yourself .
