Hello Baylee, a warm welcome to the site.
Being anxious can but not necessarily include OCD but as you haven't mentioned it, then we can't believe this to be, not unless you correct me.
Having continual breakdowns may be caused by different triggers in your life, which need to be discussed with either a doctor and/or psychologist and to overcome this fear may be you can write down each one which is a major concern for you, then all you have to do is hand over this document to them, this will break the fear of answering them when they ask you 'how can I help you'.
You can't predict a breakdown, not unless you are locked into having to do something that you can't avoid, but I have visited my psychologist/doctor precisely when this happens, it is actually the best time to talk with them.
It doesn't matter whether or not you cry, I have many times, which proves that I needed help and weekly sessions were booked, and it doesn't matter whether you see them feeling much better, but during the session, you suddenly breakdown, that's when they need to find out the cause, but they do this gently and hold back, then ask you another way.
Try and write down and book an appointment, if you want may be someone can go with you, is this possible.
Looking forward in hearing back from you.
