Stress during pregnancy

Tori
Ok so recently I quit my job due to stress and depression I just wasn't happy. I now have a part time job in retail where I'm getting about 24 hours a week. My SO makes decent money but I am so stressed that we won't be able to support ourselves let alone a baby. I'm about 11 weeks and  cry everyday. I don't have an appetite and am barely able to eat on a daily basis. I know it's not good for me or the baby but I am so sad and depressed it's killing me. Idk what else to do anymore. Any advice?
