It is hard to have interests when feeling depressed. I would ask your doctor for a medication evaluation to explore whether there may be another med that may yield better results. One thing that is easier said than done is to start exercising. Even if it is for 5 minutes a day. Start slow. Go out for a walk and appreciate the beauty nature has to offer. Build up from there and let the endorphins find their way into your life. I am sending you good energy. You can do this!
