Hi, Kira. First off I am not qualified to offer too much help but I will offer up a few words in the hope they might help you. As MrsA above suggested you could be feeling somewhat lonely at times which might be a cause of one issue. Second, to that, depression can be a difficult thing to spot as sometimes it is there and we do not know it as it hides in clever ways. Going from a room full of people and background noise to a silent room with just yourself can be such a change in environment, that your awareness notices it. This, in turn, caused confusion with your feelings that result in you not knowing whats going on with you. You mention that you are part of a dance culture and film clubs. It's likely that you are coping with your issues by trying your hand at acting in your own film about your life which is harmless enough. Overall I think you might be feeling a bit lost which becomes noticeable when you are along. Try not to be too critical of yourself when you are feeling down as this is the circle that keeps you going around and around. One way of breaking that habit is to change how you deal with your feelings. Instead of being negative about what you are doing think how things are improving all the time. You are after all going places in the world, do not let anyone tell you otherwise.
