i second @Carnivorous Spaghetti Monster's comment
live for the simple things in life, so ull always feel satisfied with what u have, which in turn leads to greater appreciation for life. even if u arent achieving great things, have an exceptionally high-status or well-paid job, there may just be tiny little things that brings u happiness which u may have overlooked in life. for instance, drawing brings me comfort and reassurance in my saddest times.
main point is, always keep a positive outlook in life. As the saying goes, "Good things come to those who wait." take one step at a time and ur bound to find immense joy in living.
Also, don't resort to actions that are life-threatening or self-harming just to escape from reality. face it, and always believe in urself.
however, do know that if u really feel at a loss or dont know how to get urself back on track, please seek help.
this is fine
