depressed

Dont get me wrong im so happy that my baby is almost here (31 weeks today) she is the miracle ive been waiting on for years. But ive felt so depressed lately and I cant seem to shake this feeling. my sister I also pregnant and my family has completely turned there backs on me but they all support her 100% because shes more financially stable. I feel like they never even gave me a chance. im a daddys girl and although me and my father havent been getting along all ive wanted my entire pregnancy was for him to be here and be happy for me. I wanted him to spoil my baby like he does for all my nieces and nephews. but I've had to do everything on my own (with the babys father) im exhausted and sad that I have no support. i dont know how to shake this feeling. i just want my babygirl to get here so i can feel better
