Please please help ASAP!!

So I put in my two weeks at my job on Tuesday. I have a another job lined up to start the 17th but my job I honestly don’t think I can go the other 2 weeks. I’m coming home every night crying cause work was so bad. It’s bad and very stressful and you get yelled at all day! And I also have stress induced seizures and I haven’t had a seizure for a long time. And I’ve been having them almost every night. It’s scary! So I’d like to start this new job Monday! But I told the new job I had to put in my two weeks. Won’t that look suspicious if I asked if I could start Monday instead will that make me look bad! Please help me! I’m very stressed 😫
