Panicking

My boyfriend and I have been through a lot. We just recently got back together after a 6 months break and I am 8 months pregnant. I panic over small stuff. I over think everything and it’s all worse since I’m pregnant. In January there was an incendent and he drank to much with his friends. He went to the emergency room and I didntfind out till the next day. Well he stopped messaging randomly that night and he hasnt messaged in a while tonight. I blew his phone up with texts and I called way over 49 times. I texted his mom and I have gotten no reply from either. He always answers my calls. Especially if I am panicking. He’s always there when I need him too. I keep begging him to cakkme because I am so scared he’s dead in a sitch somewhere I begged his mom to get ahold of him but she isn’t talking to me and we don’t get along with each. Other. I am so freaking scared and I can’t get my mind off of hjmbeing dead somewhere. I don’t know what to do. I can’t go looking for him I have no one else that can get ahold of him imso scared. I know he’s not cheating or anything like that but I know that I almost lost him in January and I am so scared to lose him I really need someone to give me ideas on how to calm down because the last few weeks have been nothing but stressful and it’s not good for the baby and I’m scared something is gonna happen to my son or my boyfriend and I’m scare d I know this isntabout pregnancy I just really need help
