This is not a question. It is something that I think people should know and should be aware of. If you're having a bad day then that's OK. It may be horrible and you may just want to leave where you are and cry but that's OK. Everyone has bad days. Everyone just wants to cry sometimes. You have to remember that there are people who care about you. It may not be clear but there are. So, don't give up if you are having a bad day. Carry on through and go and speak to someone that you care about. If you have anything to say leave a comment.
