I don't want to be another person bombarding you with questions, but this is actually a serious one. For some reason, I have no goals or desires on a day to day basis. Often I just wonder about death and whatnot. I have no urge for a girlfriend, high grades, to work out, or to hang out with friends.
Do you have any opinions on this, or any way I could get motivated?
Actually, yes.
This is something I deal with myself currently, but I force myself to give a forget.
If you're anti-social or what have you, then your personality will change, once you regain those social encounters and such, then you will regain motivation.
Say you're a sophomore in highschool, you don't give a forget about your grades, you'll do everything to rebel about your parents.
Don't just sit on your ass and fail, but rather try to get good grades, graduate, and gtfo of your parents house.
In terms of motivating yourself and preventing yourself from Self Delete;
Look at my profile comment 'Lifes a bitch, but I'm in love'. Its very true, life throws flaming piles of stuff at you every day, regardless of size, they impact your personality. When you allow them to get you so low that you want to end it all, you need to realize how beautiful life is, and I don't mean the cliche "omg babbie so cute" I mean, yeah its monotonous doing the same routine daily, but the people whom you encounter along the way make it worth living, and sitting cooped up and not doing anything just makes you even crappy feeling.
