1. I and my girlfriend broke up and she still won't leave me alone. 2. I got in trouble for making a joke when everybody else was saying worse. 3. I fell in love with someone who I could never have.
I'm sorry to hear you've been having a difficult time. You don't have to, but if you want to tell us more about these issues, it might help you work through them better. Or at the very least, you'll find others here who can commiserate and offer you comfort.
I guess my biggest problem is being in love with someone I can't have. He is a great person but he would never look at me like that not to mention he's too old for me and he is already in love with someone else.
