13 weeks still suffering

I thought most people start to feel better around 12 weeks?! I've still been suffering with all day nausea, extreme exhaustion, and just pure feeling awful all day long. I can barely eat due to the nausea, which makes me feel even worse! I have tried staying positive but I've been sick for this whole pregnancy and I'm so ready to feel normal again!!!

Please tell me there's hope and maybe I'll start to feel better next week or after? This is so rough!
