Feeling Overwhelmed: Need to Vent

I’ve been under so much stress with school starting, moving into a new apt., having to juggle possibly buying my family’s old home, and the only person I’m close to at work leaving. I’m usually able to keep calm during meetings but I was called on to volunteer for a demonstration and I couldn’t control my leg shaking and my hands shaking in-front of everyone. I just feel like everything is getting to be too much. Ontop of all of this I’m the one in charge of all the utilities and the main applicant between me and my roommates for our next place and I’m terrified that if someone doesn’t pay me for a bill on time that my credit and future will be messed up. I guess this isn’t looking for advice more just to express my stress.
