Hate feeling like this

Doctor thinks I have ppd. I'm fine during the day but it hits me at night and I just feel hopelessly sad. I end up bawling my eyes out for like 30 min. I feel so sad that my life is suddently so different. I LOVE my little boy and always will but I get so sad and just want to cuddle with my husband. My baby keeps me up all night so lack of sleep may be making it worse. I just miss how my husband and I had our routine and life and it's hard adjusting to this sudden change. I know it'll get better and sometimes that's the only thing that keeps me going is knowing that it'll be hard but it'll get better and be worth it.  My husband has been great helping me and I'm terrified of when he has to go back to work, but I'm grateful for him and I'm doing my best to get through these sad feelings.
