Okay, I promise I'm not stalking you, I just keep coming across your posts and they resonate with my life experience.

It sounds like you're putting WAY too much pressure on yourself, probably because you come from a family of high achievers. In case no one has ever told you, failure can be a wonderful thing. Failure teaches us way more than success as long as we learn from it. If you learned anything about yourself/life/the world, you won. Just apply it and try something new next time. I would suggest that you try to go for your passion again. Maybe see if you can audit a class if you don't want to commit. You owe it to yourself to try again just so you don't end up always wondering what if. If it doesn't work out, at least you'll know for sure and can move on.

You may never be able to fully open up to your family, and that's okay, but you need to get your feelings out and be heard. This forum is a good start, but talking to a trained stranger might help greatly. If you're in college, then there should be some mental health services available. Counseling/peer to peer/support groups/hotlines. Sometime talking to a stranger lets you say things you'd never say to someone you know. In the meantime, you might try to journal. Write your feelings, get them out of your head and onto paper.

I have no doubt that your family loves you and wants the best for you, they might just not know how to show/say it. Deep down I'm sure they want you to actually be happy and not just going through the motions. Sometimes those we love are just too close to see us and sometimes their own hang ups prevent them from being who we need them to be.

Please hang in there and try not to be too hard on yourself.
