I really hear you, and what you're going through sounds genuinely exhausting especially at work. The cycle of not eating enough but feeling awful when you do is really tough to manage, and it's completely valid to feel overwhelmed right now. That said, at 7 weeks with these eating difficulties affecting your ability to function, it would be really good to bring this up with your doctor or PD just to check in and maybe get some practical support, whether that's anti-nausea options or just reassurance on what's normal. In the meantime, lots of mums find that smaller, more frequent snacks (even just a few crackers or a sip of something) spread throughout the day works better than trying to eat proper meals, and keeping some bland options on hand for when nothing sounds appealing can help take away the stress of deciding what to eat. The second trimester relief is real for many, but you don't have to white-knuckle through feeling this bad for weeks.
