why is it whenever things seem to be going in the right direction i get depressed and bored for no apparent reason

Thing 1 i have my job back at walmart im greatful for that because that means ill have cash flow yet again

Thing 2 im still being responsible and paying rent... tho this time its to my folks but at least i still feel like im contributing someing

Thing 3 Ive gotten back into drawing... maybe this sad happiness is just something that happens whenever i try drawing ive even set a goal for myself im trying to make a lip sync animation and to do that ive been working on the way i work my artstyle by forcing myself to draw atleast something every other day so far im only on my first free day of it and the first day of drawing was yester-errr friday

so far i feel good about that ive been trying to draw again

but

everything else just seems boring and humdrum and boring...even the new games ive bought like Dark Souls PTD and Cargo Commander... and even....even this gaming clan i connected with to try and find more people to actually play with me and make friendships with....but i ended up throwing a big depressive fit and throwing all they gave me back in their faces and i feel bad about it now that i look back on it while im more calm
