What can i do to make my lashes look better? They straighten suuper easy and are short. Is sticking false lashes on my only hope?

i spend soo much time curling them but they seem to straighten almost right after drying, even tho i curl them like 20 seconds in different spots, add mascara both over and under, hold them up while they dry.. i use lash sensational mascara from maybelline. i dont rly wanna use lash serum cuz i often dont have the energy to wash my face if i dont have any makeup on (depression) so i dont want it being there for too long..

also i used to have extra long lashes in the outer eye corner which i absolutely loved snd they broke from curlinf them ughhhh
