Depression Keeps Me Awake

My birthday just passed, I felt like shit. I'm now 17. One more year closer to adult services. (therapy and psychiatric hospitals) Growing up is great. The supervision I'm given is now being reduced giving me more freedom in my life rather than parents watching me 24/7. It's 5am here in Ireland and I can't sleep. I don't even feel tired. I'm just numb. I haven't showered or brushed my teeth in weeks. I've stayed in my bedroom 24/7. That sounds really lazy but with my four mental illnesses it seems normal to me now. I'm so used to be this way that I can't see improvement or any difference whatsoever
