ANXIETY (possible panic attacks)

So within the last couple of months I find myself all of a sudden feeling like I’m closed in and I have no control . My chest gets super tight and feels like I’m struggling to breathe . I know it’s not just the baby taking up more space. Because this has been happening more frequent now but had happened before. The only way to fix it is to sometimes nap . I was on medicine for my anxiety prior to my pregnancy but it did not help at all. And I haven’t had attacks like these in a very long time. I get so frustrated with myself because they have been so random , at times they feel crippling . I do have a lot going on but not as bad of a life as in years past. I’m scared to talk to anyone about it and I don’t know how to help myself or ask for help. Any suggestions ?!
