I feel so alone

So as you will know after reading this post I don't have very many people in my life. I have a few friends and my close family and my fiancé... Well we have been arguing a lot cause he never wants to come home. I cook clean go to school and work... It's never ending and I just want to spend time with him here and there and it doesn't seem possible. I am battling depression with everything I have going on in my life...not to mention I really want a baby and that's been going on for over a year and nothing... But I feel like everyone walks all over me and I let them cause I don't want tl be alone. I just don't know if anyone has an tips for me? I need motivation but can't seem to get it..
