Feeling really down

Today, I'm feeling really down. My boyfriend is mad at me and I don't know why. It's Valentine's Day but I guess that doesn't matter. I'm having hyperparathyroid symptoms but my family doctor is going by the numbers and doesn't care. I feel hopeless! I wish my mother was here. She always helped me feel better! She's been gone too years! :( I'm not close to my family and have no one really but my boyfriend and an online friend. The online friend lives too far away for me to be able to go see her.
