Pretty sure I have MDD...want to be sure.

[Ty;er]

Hello,

I'm 20, and am currently finishing my third year of college. Yeah, so, I'm almost certain I have MDD, but wanted to get the opinion of people who have the disorder, just to see. Music is my main trigger. When I listen to music alone in my room, I will often start pacing around and rocking back and forth, clenching my fists, and sometimes muttering to myself as I daydream. For a long time, my daydreams were about a fictional universe I created. However, now often they are about my hometown (which is very complicated) and a guy who I had a very intense crush on until I saw him making out with another guy at the club right in front of me (still not over him). 

I've read that many people with MDD had an abusive childhood. I do not want to funnel pity to myself and sound ungrateful, but I did have a kinda rough upbringing. My parents were never married and basically my whole childhood was like they were going through a messy divorce, they were on and off together and got into awful fights. However, I think what started the MDD was an issue with my school district (here's why the concept of "hometown" is very complicated to me): my parents lived in neighboring towns, my mother just with me in the second floor of a rented-out house, and my father in his parents' basement (his brother also lived there too for most of my childhood). I was mostly with my Mom but when I started school she enrolled me to my dad's school district since her district was considered bad. When I was in 7th grade, my dad's district caught on to the scenario and had some retired cops/private investigators stalk me and film me to see which parent I lived with more, and threatened legal action unless my Mom transferred me to her local school district. Instead my Mom moved very abruptly into the "good" school district, and I didn't even really get the chance to say good-bye to my childhood home. 8 years later, moved 3 times since (not including college), and I still think about that event and how I could have prevented what happened from happening (my family blamed it on me for a while, believing that I must have accidentally mentioned my address situation to a teacher or social worker). The habits I mentioned before that I believe are symptoms of MDD started almost right after the move.
