Are there anime versions of the shoujo manga you've read? Have you tried watching them? It goes along with what a lot of other people have said - listening to something that you're already familiar with is easier. If you understood most of the vocab from the manga, you'll probably know most of it in the anime, and you'll have context to help. By a few episodes in there would probably be words and phrases popping out at you.
If it makes you feel any better, my listening comprehension is still fairly crappy, and this is after 3 years of college Japanese classes, over 4 months total of lessons at a Japanese school in Japan, and countless hours of watching anime/dramas/plays and listening to music. At the school in Japan, my distaste for the classes when we listened to dialogues/audio readings from the textbook led one of my teachers to start calling it my "好きな聞く練習" as a joke

But there are two important caveats to this:
1) I have listening problems in English a lot, too, and that's my native language. My mind wanders way too easily, so focusing on an entire boring audio snippet is really difficult, especially if there are words I don't recognize right away. When I watch things in English I usually have to rewind parts to catch things I didn't hear or wasn't paying attention to, and it's the same in Japanese. During those 聞く練習 classes the teacher figured out that if she only played little parts of the audio at a time, and if I knew what I was listening for, then I could understand it just fine. I just needed to hear it more than once, and at my own pace.
2) It probably sounds like I've done a lot of studying without much to show for it, and that's not entirely true

One of the main reasons I have trouble with listening is my vocab is still too limited, mainly because I think vocab is pretty boring. Given something that I'm interested in, and the ability to replay audio if I don't catch it the first time, I'm usually pretty good at
hearing a sentence, even if I can't quite understand it. I've looked up tons of words just from hearing them.
My main points in relating all of this are: Don't be too hard on yourself. Listen more, listen to things that are interesting, listen to something as many times as it takes to hear it, and increase your vocab, because the more words you know the more you'll be able to hear even when you don't know them.

It's too bad you don't like Japanese music, because that could be incredibly helpful, I think.
And to end this overly long post, here are some links that may or may not be helpful:
http://www.voiceblog.jp/japaneselistening/ -- Two guys having normal conversations in Japanese. They cover some pretty varied topics.
http://japaneselistening.blogspot.com/ -- The transcripts/translations to some of the audio.
These are just regular conversations, so they're unstructured and the vocab is all over the place. But they're kinda fun to listen to.
Good luck!
