I was recently diagnosed with major depression and have been diagnosed with depression since I was 14. I struggle very much with it every day of my life and it affects every task I complete, or don't. For me, depression:

• ruins my life
• makes me mean to my boyfriend
• makes me so tired that I sleep all the time and sometimes even can't sleep, so I just stay up, exhausted
• makes me lose weight (my boyfriend constantly yells at me to eat when I have my depressive episodes)
• makes me stay inside and not even go grocery shopping let alone to events or parties
• makes me ignore my friends' messages and decline event invites automatically on Facebook
• makes me long for things that are right in front of my face, for example I will feel more lonely than I've ever felt in my life yet my boyfriend is cuddling me and showing me affection, etc
• makes me have no respect for my body
• gives me low self-esteem; I hate myself and see nothing good, no strengths, no skills, no redeeming qualities in myself, just nothing but a waste of space
• lowers my grades by making school feel impossible for me, or making it impossible to care about school, or both
