Worried and stressed

Hey mamas! I’m 29 pregnant with my second child and wanted to ask other experienced moms if any of their children’s came out fine and happy while going through a lot of stress during pregnancy? I’ve been trying to keep myself stress free but it’s been hard since it’s my first time away from family, this pandemic, relationship issues and staying home with a toddler all day has been so hard on me. I’ve been googling it and all I find are others who said they ended up having difficult babies who would cry all night or articles stating ADHD etc. I’m so worried my anxiety, stress and anger throughout this whole pregnancy has done something to my baby :( Any answer is appreciated, thank you in advance :)
