Anxiety. ( long)

My cars been acting up the past few weeks but has been getting a lot worse. I haven't had the time to take it to get looked at, I mean hello I need my car! So yesterday I finally decided okay today is the day my fiancé was off work so he could go to take me home after dropping it off it was perfect. I was a little nervous about the 30 min drive to the shop where it's getting looked at but at the same time I've been driving an hour to and from work everyday for the past month in it. It was doing so so good, like so much better than it's been in weeks. I turn onto the street the shop is on and it was over. I couldn't get the stupid thing over 20mph without it going up to 7 rpm. I pulled over and told my fiancé it just needs to sit for a few and it will be fine( it's normally a lot better after it sits) well I go to start it again and it won't even start! It's not had a problem starting the whole time I've had it, why now!?! I'm in some random neighborhood like or seriously?? I call aaa and they come to tow my car. He calls his mom just to give her an update on what's going on while we waited, as soon as I heard him explaining the situation i lost it. I could not stop crying, more than that my chest hurt. I stepped out of the car to walk get some air and just chill, I got myself together and went on. As I see my car, my baby, on the tow truck I lost it again. I got in the car and just refused to keep watching. The shop was seriously a mile away so we get there and he goes in to talk to the guys there I just sat in the truck. I see this tow man taking my car off and just leaving it in the parking lot. He doesn't ask where to leave it just takes it off his truck and leaves, doesn't say a word. I start to panic thinking how are they going to get it where they need it? At this point I can feel the panic attack coming. I call my best friend and she just talks to me, she's really good with helping me just breathe when I just can't anymore. I get calmed down and Andrew, my fiancé gets back out in the truck with me. On the way home I again lose it just thinking about my family and how much they mean to me. We are pretty messed up but seriously where would i be without them? He just looked at me and goes, you got a baby in there? I then started to cry laugh thinking maybe! I've never had anything like that. I've had a panic attack before but it's never been like that. Every little thing yesterday I couldn't handle. I was so emotional. Not only that but the rest of the day I could not stop shaking. I just wanted to share incase anyone else understands?
