Feeling miserable

I'm currently 5 weeks PP, my birth was easy and painless, it hasn't been too hard learning how to be a mom and my baby is the easiest baby to take care of however, I feel extremely exhausted even though I get enough sleep. Its exhausting to leave my room and my biggest support is my husband but hes getting deployed for a year. I'm going to be alone for a year and even though I have family and friends I still feel completely isolated like I cant go anywhere or do anything with the baby. No one cares to listen to how I feel because they assume motherhood isn't hard for me just because I had an easy delivery... very frustrating:/
