What would you like to receive here on this forum? Advice? Emotional support? Or an answer to your question "Am I overthinking?" I can provide an answer to your question. Babies require tender loving care seven days a week. Preferably by both parents. So, no, you're not overthinking anything. And, even though you didn't ask: Because your baby's father could have something serious, at the very least he should call his doctor and describe his symptoms.
