I don't know who to turn to...

My mom, is (I guess I should say "was) my best friend. Earlier today we got into an argument over my baby shower. I didn't like that she was Inviting people I didn't like/want there, but apparently I was in the wrong for that. Basically, I'm no longer having a shower because, she refuses to host it. We had this fight 5 hours ago. I turned my phone off and just took some time for myself. I just turned it back on and needed to ask her a question and she refuses to acknowledge I texted her. I suffer from really bad depression, without her I feel worthless, and like I have no one in my corner. It's taking me all I have right now not to break down and cry. As I'm sitting alone in the dark, with no one to talk to or to comfort me. I know it's selfish because I'm growing this beautiful baby, but right now I feel as though life isn't worth it. (I know this may seem a little dramatic but a lot more happened besides the shower fight, I just don't feel comfortable sharing details.) I don't really need advice or anything, just needed to vent and maybe hear some words of encouragement. Thanks. 😕
