Hey sweetie, I hope you're feeling a bit better now. Sometimes we just need some time to ourselves to work through things, but at a certain point, you have to put an end to that period and just make a change to shake things up a bit. The more time you spend in your PJs in your room, the more likely to spiral into depression. But, you have a lot of friends here who care about you and we all want to see you happy. I agree with everyone who suggested a change of scenery, as going somewhere different, even if it's just for a day or two, can revive the soul. Of course, making up with that lovely sister of yours must have helped a little.
