Awh don't worry there will always be people to talk to who can help, you just need to look a bit harder for them sometimes. Like the people above have suggested, talk to a counselor or doctor or teacher, someone you can trust, and they should be able to give you some helpful and reassuring advice. Whilst it may seem like your education and career is over, it's most definitely not, and you've learnt a valuable lesson which will really grow and strengthen you as a person. Many people have been in your same position, and I'm sure many have them have turned out just fine. From experience, the saying 'a problem shared is a problem halved' is very true, so for now even if you only feel like confiding in a couple of close friends, it will help.
