Depression

Right now has been the hardest time of my life. For the past 6 years my dad has had cancer. It’s been a journey but it seems that we’re looking at the more positive side of this and he will be having a bone marrow transplant which means he has a chance of going into remission. My grandma has had cancer for about a year now and she is near the end of her life. She was so close to me it hurts to see her so sick. With all of this, my boyfriend of two years broke up with me because of a band he’s in. I was in love with him. With all of this going on my life seems to be falling apart and I can’t seem to bounce back. Sometimes I try to occupy myself and get out with family or friends and I am ok for the time being, however at any moment I snap back into my reality and become depressed again. I’ve been depressed before but usually snap out of it, however this time I cant. I don’t know what to do. I don’t know when things will get better or if they ever will. Anyone have any suggestions to get over a bad breakup? Or anyone dealing with similar situations?
