27 weeks and started again now struggling.. 😞

I'm a FTM and smoke marijuana daily previously when I found out I was pregnant at 4 weeks I stopped cold turkey. I got so sick and depressed I wouldn't move from the bed wouldn't eat and wouldn't drink anything.. I had such high anxiety I quit my job of one year after a blessed promotion. I was struggling with eating and a family member suggested I go back to my medical marijuana so I did. Now I'm 27 weeks I only use half a gram a day when I'm feeling crummy. I want to stop. NOW. But I get sick sad and don't eat. I'm so scare! Someone anyone help. Please don't bash me I'm really scared for my health and how that will affect my baby..Â
