Hello Jess.
I am sorry you are having a rough time at this time. You have suffered a very traumatic event and you are still mourning ths loss of your grandmother at this time. Is there someone you can talk to such as a school counselor, or do you see a therapist at this time. Sometimes it takes a while to feel better and less depressed after a loss of a family member. Journaling is also a good exercise as well for depression and loss. I hope things get better for you soon. Take care Soidhonia
