Just had a super stressful day and i need to vent

I have major health anxiety all the time. Its what makes life so hard. Today i woke up in a trance and at 2pm, i had a filling for one of my teeth that turned into a root canal in a few weeks. That alone already put stress on me but at the same time, my family just went on a ski trip. I cant because i have work but now im alone at home with nobody to help if anything goes wrong. My back hurts all the time from stress and poor posture and i have a nicotine addiction with zyns. On top of that i know that tomorrow i need to get to work. Im not ready to wake up early to go to work. Anxiety is compounding and i never sleep well because of it. On top of that, its winter and i absolutely hate sitting inside but i hate the cold more than that. Im working in staying in shape and being active at home but its hard to stay happy in my situation. Im also new to the workforce after graduating college this december after a long and bumpy college career. Stress is at an all time high lately and i just want to feel free and happy.
