PostPartum Depression

Hi guys I’m 19 years old and I just had my baby girl about 3weeks ago and I think I have postpartum depression. The whole pregnancy was really hard for me I dealt with a lot of mood swings and financial struggles with my boyfriend. The first few days home from the hospital I was happy but it was extremely hard to adjust to my new life as a mother. I love my baby more than anything on this whole earth she is absolutely everything to me and honestly the only good thing I’ve done with my life but for some reason I’m extremely sad everyday. I can’t stop crying I have no appetite I never shower or tmi... go to the bathroom. I also can’t help but resent my boyfriend I feel like I hate him and everything he does really sets me off I almost feel like I’m not in love with him anymore. Is this normal or do I just really not love him? Do you guys think this is ppd or normal baby blues?
