I suck at pregnancy :(

Ever since I can remember, I wanted nothing more than to be a mom. I was so over the moon happy when I found out that I am pregnant with our first baby! I'm now 12 weeks and 2 days and feeling quite terribly about myself. I've had morning sickness that gets worse and intensifies with each passing week. I feel like I'm failing at motherhood already! I've tried everything: eating before I get out of bed, eating every few hours, lemons, ginger, protein, mints, etc. You name the remedy, I've done it and nothing helps. I struggle to eat (the look, smell, taste, texture of all foods makes me gag) so I try to force down what I can for baby. I feel so tired and nauseated all day :( I've missed a ton of work (more days than I have) and feel like I'm getting judgement from everyone. My boss keeps telling me "when I was pregnant both times I never got so sick I couldn't work." My family and friends say "morning sickness is normal, it'll pass." I see pregnant women on here posting about workouts and how much energy they have and I can't help but feel like I'm doing a terrible job over here. I just want my baby to be healthy and happy but I'm stressed that I'm weak and baby is going to suffer from my shortcomings. Anyone else feeling like a failure? Or has anyone else gone through something similar and have everything turn out well for their health and their baby's?
