loving parents that are grateful for me to exist

Whoa. This is pretty much like no other day I've went through. First off, it all started this morning when my mother wanted to see if I was going to pass any of my classes. Then, we had a bad argument with my parents that I didn't appreciate (about making a living off of doing a non-singing career). I was so mad that after I went to my home for a little bit, posted an angry note at the front door (to tell my parents where I would be), and took my Introduction to the Internet book with me to use it to study for my final that will be coming tomorrow. I did some studying in a building that I like to go to. At about 5:00 p.m., my father came to pick me up at the building. We had a conversation, and during it, he said that this will probably be my final term in the college (and it's really a big possibility, due to the increased difficulty of my classes, lack of friendly representation within the college, and possibly failing grades), and that I will be able to do something that will help me feel needed and wanted (and as far as I know, attending college is just not helping me do it). My mother was very worried. She was crying, and was very concerned (and she was definitely in the right mind to do it, because she is my mother after all, and women have a right to cry, don't they?). Both my mother and father told me that they love me, and that even though they may really blow it sometimes, and may have temper tantrums (or something of the sort), they love me, and nothing can ever change that.
