multiple times during the week usually depression is the reason, i have interviewed many shorter people getting to know them i have found out many are the same when dealing with life. it sucks i just tell them to eat more and do more. you cant do more without eating more, alot of smaller people dont get that and just let there depressive emotions take over. i can empathize with them is that life doesnt seem to conclude but they need to empathize with me that you cant be depressed and sleep all day and not eat. ALOT of people do this , this is something not talked about often
