oh my goodness, let me tell you that i can wholeheartedly relate. i'm so sorry you're going through this man. i literally spend 80% of my waking hours thinking about how my skin looks: avoiding certain lighting, visualizing how gross i look, avoiding mirrors like the plague, standing/sitting in places that will cast shadows on my face. i also broke out on my right side last December. it was bad, but it's cleared up until recently. now i've started to break out on my left side, which was what i was fearing. my skin has also been ridiculously oily recently-- within two hours i begin to shine bright like a diamond and i hate it.
so no, you are definitely not alone. my cheeks are covered in dark marks too, my pores are enormous, i'm breaking out, and i feel like a hideous, greasy mess. i don't want to leave my room. i recently slept over at my friends house, and when i wasn't wearing any makeup i could see her mother scoping my scarred face with pity. it makes me feel like shit, so i can completely relate to wanting to pass up a holiday because of your skin. i just hope it gets better for both of us, because i can't imagine living the rest of my life like this. i'll stay strong if you do too
