You cand either get some help with wacthing her, either from family, friends or day care, or you can suck it up and take care of her yourself. Those are your only options. Being a stay at home mom is difficult, there's no doubt about it. But no matter what you're going through your first priority is your daughter. I know it can be lonely, it can be isolating and it's a 24 hour a day job. But, it's your life, you have to just have to do it. It's not easy for me to take care of a 3 year old and an 18 month old while keeping the house clean (which I generally fail at), cooking and all the meal and budget planning that goes with it, while being pregnant. But I do it because I don't really have a choice. Yes, my husband is "only" in school and is home every night, but I do my job to the best of my ability because I know I have to. I've had to deal with my husband being away at times and it's been weird and a little difficult. So for you, since you'll be without your husband for an extended period of time, the best thing would be to have someone else take care of your daughter for a couple of hours a day so that you can have some time to yourself.
