So there's a part of me that's just like... "memes?!" when there's another side of me that says "do not take on more because you can now. The event is coming up soon"
It does sound like a mental health thing. So try to just be kind to yourself and take it easy. Long-distance relationships are rough and take a lot of patience and trust and they can be very mentally and emotionally exhausting. It’s fine to not do anything for a day or two. You’ll shake off the blahs eventually, give it time, it won’t last forever.
