Why did she block me?

OK so I've known this girl for a while and I like her, a while ago she got really depressed and she said she needed to be alone for a while, so she blocked me on snap because I kept messaging her everyday to make sure she's OK, but, I'm still messaging her on several other apps/social media and she is still ignoring me but she hasn't blocked me on anything else, cuz I thought she wanted me to fuck off, but if she did want me to fuck of completely and cut me off permanently, she could block me on everything in 2 minutes and be done with it so I don't know wtf she wants.
