Im tired of my life now....i want to die....what should I do?

Throughout my entire life i've just been suffering, and suffering, and suffering. For 4 years I was just moving around from house to house to hotel, for another couple of years I was just suffering from anxiety and worry because there was just so much trouble in my life. For another couple of years i suffered from bodily discomfort, boredom, anxiety and worry, and it mad my life near impossible. and now for another 3 years i am once again suffering from worry, anxiety, bodily discomfort, boredom, confusion in my mind not knowing what to do, and now im sick of it. Everytime I try and imagine something that i would like to happen, my bodily problems and my worry and my endless anxiety spoil the experience. I want to die. I'm so fed up with my life right now, so I decided to post this, in case it would help me, Im sick and tired of my life now, so what should I do?
