I feel like I've lived the best years of my life and probably not to it's potential but I feel like there's nothing else to look forward to. I just see old age and illness and loss. Both my parents are fragile and I just feel this incredible sense of dread that they won't be here for much longer. I just feel like I'm done, I went to uni, got married had children who are now teens and now what else is there? I've made choices which have led to this life and career that I hate but I have no motivation to change it. I'm just tired. Life is just tiring and boring, I literally have lost enjoyment in everything that's once brought me happiness. Is this normal to feel this way when you get to this age?
