My, what a lovely Venus you have.
I agree with RosieOne, Saturn isn't being very kind to you right now. If you think in terms of whole sign houses, where the entire sign is the house, he has recently entered your 12th and is approaching your Sun. The 12th isn't called the house of self undoing for nothing. You might want to look a little more into Saturn transits to 12. It also doesn't help that your ASC ruler, Jupiter, is currently retrograde in Gemini/your 7th.
Saturn will cross your natal Sun and Jupiter will go direct at the end of January into early February. There might be a little easing of the pressure you feel then.
Again agreeing with RosieOne, you do need to try to keep a sense of humor about Saturn transits because they are very hard. The thing to focus on is that it is, well,
transient. It doesn't last forever.
And though at 15 it's difficult to put it into perspective because you don't already have the experience of how to deal with it, whatever lessons you are learning now will serve you for the rest of your life.
I would try looking into that wonderful Venus of yours, and to spend more time focusing on what is positive. And read the links JUPITERASC has provided, if for no other reason than to see that you are not alone.
