Anxiety and depression. Day. i have ocd!

Hello, For past few months, I feel like I am suffering from anxiety disorder and mild depression. I have lost all enthusiasm to work or watch a proper movie. I have gained much weight and my anxiety is increasing day by day. I have OCD regarding certain issues as well. I have this underlying rage in me which comes out at unaccounted times. I have this burning sensation of defeat and hopelessness. I have recently suffered a loss of a family member who was close to me and I am not sure how well I am taking it. At times I cry to sleep and at times it doesn't matter anymore. I don't know what is going on but something is very wrong. The bittersweet moments of my life are turning out to be my nightmares ! Thank you
