Extremely tired

I’ll be 12 weeks Tuesday and it seems the past 2 weeks my symptoms have worsened. Nausea, headaches started and really tired all the time. I can’t walk 5 feet and without feeling exhausted. I’m a little overweight but overall healthy pregnancy. This is my second and this pregnancy has been totally opposite than my first with my son. I guess I feel like I’m being lazy or something since my SIL is also pregnant and 18 weeks and is is basically perfect, cooks dinner every night and keeps up with her 2 year old, just peppy. While I’m over here feeling like I’m a big ball of blah bc I’m not doing everything I normally do. I’m over here like we’re surviving that’s it nothing extra. Anyone else feeling so tired still?
