Lonely Pregnancy

Has anyone ever felt alone during pregnancy. I just want my son to have the best life possible & I feel like I’m not doing a good enough job. I feel no support from anyone around me. I feel like no one understands me or how I need emotional support right now. I literally feel so alone with the exception of my son who’s inside me. My dad constantly dumps on me with his problems & him & his wife tell me how messed up I am all the time. My dad tells me how calm my mother was during pregnancy but my mom has had a serious drug problem my whole life, to the point where it deeply affected my childhood. I just want to be the best mom I can be. I need help!! Even my husband says terrible things to me & is disappointed in me with the fact that we never have sex & he doubts my capabilities as a mother. I don’t know what to do anymore. I feel so lost & depressed. Any advice, please help & don’t kick me when I’m down.

In case you can’t tell I have a horrible family dynamic & nobody on either my dad or moms side speak to each other in the entire family. I feel so hopeless, except wanting to be the best mom I can be.
