Pregnancy Forum - 2 Anxiety Attacks In 1 Week

You read right. I have had 2 anxiety attacks this week. I am 38 weeks + 5 days now.
Anxiety attacks aren't too common with me, but I have had 4 before, and they were all realllllly bad.
On monday I was in the hospital because I thought I couldnt breathe and my chest was closing... They did all these tests & xrays on my heart/lungs and absolutly everything was fine and they concluded that it was an anxiety attack from all the stress I have been under. So I tried to take it easy this week.. Not leaving my home, not dealing with any family issues, etc
and then yesterday happened. I am sitting at home and I get a knock on the door, I look through my peep hole and there was two guys and they looked really scary ... I didnt understand why any one would knock on my door, I have no buzzer. One of them looked like my ex bf who was very abusive towards me physically, verbally, and emotionally. I still am not over every thing that happened and I am still very scared of him, and any of you who have been in a relationship like this when you feel threatened for your life (and I hope none of you have had this experience) you know how I feel. The guys stood outside for about 5minutes and when they left I asked my building manager if anyone was complaining about noise , and he checked the surrounding appartments to me, and no one did. So then I got even more scared that it was in fact my ex who came around (and I still am..Havent even been home yet) ... I cant even type it out how bad my anxiety attack was last night. The last time I had one other than these 2 were last year when I was still in the abusive realtionship. I still feel scared and super stressed out and I am worrying for my babys health in there.........

Has any one had anxiety attacks so late in pregnancy? If so how did you deal with it ? And is there any advice for me to get through this all? Thanks

ps- I am posting here because my family doesnt understand how my ex's behaviour really affected me. They think I am just over reaacting. And they cant seem to tell how stressed out I really am.
