Pregnancy depression ??

Has anyone had this? I’m 14 weeks and all I can do is cry because I’ve been so sad and feel so alone. I don’t really have many friends (literally 2) and really no family… I don’t think that’s why I’m sad. I’m not sure, I’m just sad everyday for everything and cry and cry. What helped? Any advice? Idk I just feel really alone…. My husbands here but works alot and we have other kids so not much time is actually spent together… idk I’m just having a really hard time and when I try to reach out to those around me they seem to just not take it seriously and it’s making me feel unheard and unseen and just way more sad. I hate that I feel this way. I wanna be happy. But it’s like idk how to be I only feel sadness and I’m not even sure why.
