Lonely preggy

It's my first time to get pregnant after a year of being married. I have always been overweight and was actually on long vacation (quit my job) to get fit physically and emotionally. To be honest, i was not sure if i already want to have a baby but my husband really wants to already so i prayed to God that if He thinks we are ready, His will be done. I'm exactly 7 weeks pregnant right now and all i've been is moody mostly sad. Thankfully no morning sickness but no appetite as well i only eat to avoid headaches and ulcer and i take vitamins for our baby. I am watching my weight and i havent gained much really, 0.2lbs to be exact. I'm just so sad and lazy and i want more attention from my hardworking husband. I am just so down and i need someone to tell me if this is normal.
