Hi! You do not have to say anything, just being here is perfectly fine.
Hi to you too, hope everything is as fun as it was back then. ^_^
It really depends on the person. Some listen to music purely for the sound, considering the lyrics meaningless compared to the harmony of the music itself (Some bands, like AC/DC, are built on that concept) while others need the lyrics to mean something to them to enjoy it. Most are in between and some are entirely different, but there is no inherent harm in any of them. Just enjoy what you enjoy.
It is a good idea to be careful not to play something loudly that others may be hurt by, or to give the impression that you support something you oppose, though. Perhaps you could wear headphones for the stuff you are afraid may cause someone to be afraid or hurt? That way, you can explain your opinion if anyone asks. Or you could get a shirt with a message about it! ^_^
Bear in mind that I am a very lyric-central Kobold who does not like Hip Hop, so my opinions are not without need for salt. :3
SpoilerHope it gets better soon, it is sad to hear that it is still so hard for you. It does show that you are an incredibly amazing person, but it is sad all the while.
Congrats on the dresses, they look preeetty. *w*
