Ate, ang hirap talaga ng situation mo at totally valid ang feelings mo, pregnancy hormones combined with stress at exhaustion is isang malaking storm, kaya don't beat yourself up. A few of us went through the same thing, at what helped was having a serious (but calm) conversation with our husbands about how we literally cannot manage the house, toddler, AND pregnancy all at the same time, so they need to step up on specific things like washing their own dishes, make it about teamwork, not blame. The guilt you're feeling after losing your temper is normal, pero important rin na you take care of yourself first (rest, eat, hydrate) kasi pag overwhelmed ka physically, ang emotions ay mas malakas. I'd really suggest checking in with your OB about how stressed you're feeling, especially the stomach pain, sometimes stress during pregnancy needs proper support. With your toddler, a quick "Mama was upset, not with you" and a cuddle goes a long way, pero honestly, managing your own stress first will make everything easier. You're doing your best in a very hard situation, sis.
