Just need some love

I am 25 weeks and over the last few months lots has happened in my life. My husband has developed depression and anxiety and he has had episodes or season of it throughout his life but it has reached a really bad level. He swears it's not because of the baby as this was a planned pregnancy but instead due to his work and parents who are drama staters. I have also had the extreme morning sickness and had to quit my full time job to part time to be able to manage. We have both really struggled alot and I love him so much. Lately tho I just feel like I'm putting out so much more of myself than what I'm getting back. He is stretched thin so I dont want to ask for help or time because im scared its just gonna make his problems worse. How do I deal with this because I feel like I'm doing this alone the prep and planning, the doctors appointments like legit just life in general all alone and its wearing me down. I just legit dont know what to do because there is weight from issues neither of us can carry but there is no where else for them to go
