Feeling so alone...

When me and my husband got together things seemed like they would always be perfect but it has not turned out that way. We have a child and she is my world we are currently ttc our second but he keeps saying we can have a second one but he doesnt really want a second one. that breaks my heart because I have always wanted a big family but agreed to two because he wanted a small family. On top of this we have a lot of problems going on at work etc. I dont have any close friends anymore to turn to and dealing with all of this on my own especially now that my family seems to prefer pretending I dont exist. I am so tired of trying to figure out what to do by myself and having no one to turn to. I feel like I am holding my whole world together with a piece of unraveling string and have no one to atleast just let me get it all off my chest.
