my only friend dropped me because of my depression

i (f16) just got dropped by my only friend we’ve known each other for about 3 years. she was my only friend, and she knew that. as friends do, we vented to each other whenever we needed to but she recently messaged me saying that she didn’t like me anymore and that i drained her because i’m always depressed. i feel so guilty, angry, and alone. i no longer have anyone to talk to and i have no way of making friends (im homeschooled. i’ve tried making friends online but it didn’t work)

does anyone have any advice for me? i’m so alone and depressed idk what to do
