Feeling like I’m not made for this

I have been feeling so guilty lately at how much I dislike being pregnant and how low I feel all the time. I am going through major depression, insomnia, and just about every pregnancy symptom you can think of and it has taken a toll on me over these last 8 months. I have been crying uncontrollably for weeks and just don’t feel like myself anymore. I feel so bad for my significant other because I don’t even recognize myself and I feel like I am weighing him down so much. I am going to therapy and taking medication to care for myself but haven’t felt any relief. I hope I am a better mommy than I am pregnant woman because I feel so guilty for feeling this way. My partner doesn’t understand my depression and keeps telling me that when the baby comes I’ll feel happy and I hope that is true.
