How do I keep my sanity through the purge

I've been on treclin 0.025% for about 3 weeks now, using it every third night. My acne has just exploded. It's the worst its ever been in my life (and considering its always been classed as "severe" by doctors - you know its bad). I truly feel completely soul crushed. It's all I think about all day and I can't avoid thinking about it because it hurts to talk and eat and I can see it in every reflective surface even just the edges of my phone. A lot of days I wake up, look in the mirror and just burst into tears. Some days I spend all day intermittently crying about it. I know I just have to keep going and wait it out but I don't feel like myself at all. I've always been a very confident person, even through the pits of my acne but now I just walk around staring at the ground in public if I'm not wearing makeup. I know I'm not even at the peak of the purge yet so how do I get through the next few weeks without completely losing my mind?
