I have this constant feeling of restlessness this past few weeks like I'm constantly waiting for something and my thoughts and heartbeats are haywire. I also feel depressed pretty often at random times in the day. I don't really know whats the exact cause of this feeling but its driving me nuts. I don't think my recent break-up is the only cause of this. I think partly not knowing about what university I will be in, feeling unwanted and unloved and just unhappy and unsatisfied with myself. I don't know how to get my head to not be this way. I try and go out with friends as much as I can, to just distract myself from my thoughts but at the end of the day, I end up the same. Whats wrong with me?
