Postpartum depression

I think I have postpartum depression. My baby is 11weeks old and I love him to pieces. He gives me purpose but I’m always so scared and so sad unless I’m with my baby. I love my husband and he’s a great dad and loving husband but he now thinks I don’t love him anymore because I’m always mad or sad or just annoyed with him. My husband has always been goofy and a jokester but now every time he tries to mess with me in a funny way like he used to I get so angry or sad. He gets upset and thinks I don’t love him anymore. I don’t know what to do. I feel helpless and worthless. I’m always worrying about something bad happening to my baby (not me hurting my baby) and I’m terrified and I don’t have any friends, my best friend “broke up” with me because we have different views on parenting (she’s anti-vax and I’m not). My sister doesn’t talk to me because she hates my husband, my mom just lost her father so she’s going to through her own thing so I literally have now one to turn to. I can’t talk to my husband about it because like I said he just gets upset and thinks I don’t love him anymore. I’m lost. I requested an appointment with my doctor but it’s Sunday so I’ll have to wait until tomorrow to get a response. I love my baby and my husband and my fur baby so much and I feel like I’m losing my little family because I’m not okay. I just needed to vent. Thank you if you got to the end and sorry it was so long and all over the place.
