Wow, i was surprised how upset (sad) i felt reading your first post in the thread. You were so helpful in my thread i was surprised to see you like that here. I know we're all on this site for a reason, but i was still caught off guard.

I did feel a bit emotional reading it, which is odd for me to feel that way under these conditions. Hopefully you're still feeling better, and maybe knowing what a help you are to others will help further.

As far as your situation, you're doing better than i am. I only went to college for 9 weeks (junior college at that) before dropping out. And i wanted to quit sooner, but i was too afraid... of disappointing my parents haha. I think i had given up on trying to find anything by then.

It wasn't until i was in my late 20s/early 30s i found something i was good at and had an interest in. But i was homeless and having severe depression and a short while later, panic attacks. Other things happened and i never got my chance. But if you've gone this long in school, even with what you're not interested in. That's actually a good sign and a quality i'm envious of.
And now you're using wisdom to realize you need to make a change. That's nothing to be upset about. That's smart. Nothings ruined. Quite the opposite. Ruined would be finishing school and hating what you do before you even start, because you were afraid to stop.

Don't let fear convince you your wise choices are wrong. Be proud for knowing yourself well enough to know when a choice is bad, and for being strong enough to stop it. If i'd had that capability i could have saved myself a lot of heartache over the years.

Perhaps take some time to think about the things you most enjoy, make a list. Then begin researching the kinds of jobs that could fit with that.

Or you could consider taking a Briggs/Myers personality test and they often have career suggestions for people who fall under the type you get.

I couldn't use that, but found the answer very self enlightening. Perhaps you could get both out of it?

Either way, don't worry. Something will come to you eventually.
