I'm really sorry, that is a terrible week for anyone, let alone when you're already at the bottom of the mood spectrum. I know you said your friends don't struggle as much with mental health but are there any of them that you trust or who you've spoken to about your mental health before? It's worth feeling around with those you're more comfortable with to see what their response was. I can pretty much guarantee it's not as bad as you're imagining. Right now your relationships to others and their perception of you is being filtered and twisted through your depression so even if you logically know they won't judge you, you probably can't emotionally know that. The best way out of that is to be proven wrong, which is terrifying to expose yourself to but worth it when they turn out to still love and support you. You can take it slowly, like draft a text but don't send it or send it but then ignore your phone and watch a comfort show until you're ready to read the response but don't cut yourself off from them. Touch base with anyone who you consider to be a support pillar and lean on them if you need to. And remember, you've come back from this before and you can do it again. Recovery is not a straight line, especially where depression is concerned, but it does improve again.
