I don’t know what to do….

I’m currently at work, my back is killing me, Still, I manage to keep a normal expression on my face, but I’m in pain, my back has been hurting me for the past 3 days and it’s just getting worse, I’ve put icy hot to calm my muscles but still, the pain is there. Last week my hair began to fall out so much, not just what you would expect, like if I run my fingers through, I’d pull out about 20 each time or more, it’s scary, I’m so afraid of brushing it now. Is it because I’m stressed out? Last night my ex called me which I’m am trying to forget, that worked out good because when I heard it ring, I just walked away from my phone, I’m going through such a hard time with my parents constantly fighting blaming each other for stupid things, it’s getting annoying. Everything around me is just pathetic, Like I wanna scream out for everyone to shut the hell up and leave me alone. I’m stressed! my hair is falling out! I don’t know what to do to keep people happy or to make myself happy.  I don’t even wanna eat, and I haven’t. I stopped taking my thyroid medication because I have to pay rent soon and I don’t have enough money to keep the medication going, so that’s gonna make me have mood swings. This is all getting to me 🙁
