horrible panic attack

my worst fear almost happened. everything was going okay today. i havent been sleeping at night much because of switching my meds, i think...and i get horrible headaches at night and feel so hot its just extremely hard to fall asleep. so i ended up going to bed around 10:30 this morning and woke up at about 6pm. my mom woke me up to make sure i was doing okay. and i felt pretty hungry...so i made myself some chicken and peas. while i was eating, maybe 5 minutes into it...i felt like i was going to have a panic attack. completely out of nowhere, i was fine a second ago! i felt like i was going to be sick and that is my worst fear ever that has been controlling my life. i got up right away and knew i had to take a xanax otherwise this was going to be a bad one. i screamed for my mom to come out on the balcony with me (thats where i feel better, outside) and i told her i was having a panic attack and she came out with me. she tried sitting next to me, but i felt even worse having someone close to me so i told her to move further away (she's used to this stuff, shes been through most of my attacks) she was trying to tell me to breathe. this whole time i feel like throwing up which sparked my anxiety WAY more. so i started dry heaving really bad...it lasted for about 15 minutes then passed without actually getting sick. it was the worst feeling that ive had in so long. i was so afraid. i know i need help with my fear of throwing up  because it IS CONTROLLING MY LIFE. it has been for over 10 years. i dont know what triggered it...it was so strange. a panic attack this bad with dry heaving has only happened twice before withing 3 years. it took about 30 minutes for myself to calm down again. ugh, im exhausted now. its so weird how my body just changed withing a matter of seconds. i was sweating even though it was pretty cold outside, my nose kept running (idk why, it happened the past two times this whole dry heaving thing happened), my eyes were pouring out tears, but i wasnt crying it was because of the force of the dry heaving, my whole body was tense...even my fists and toes were clenched tight. its concerning because my heart rate goes SO fast and im scared of what all this is doing to my baby! this cannot continue to happen! my emetophobia is ruining my life and hurting my baby!!!!! i dont know what kind of help i can get...it seems so hopeless to get better. id get hypnotized for all i care to help me! im so exhausted now. thank god for my mom, she is so amazing and im so glad that she was there for me to help me...words cannot express how much i love her and hope im such a great mother like she is.  i just need to fix this somehow. i want my life back!  ....im scared to eat again even though i only ate a few bites of chicken and some peas...i dont want it to happen again. but i know i need to eat for my baby....omg this is so hard. i dont know if its from withdrawling from my meds, and i still have a bad chemical imbalance, then on top of taking my new medicine zoloft, and then not smoking which has been a tough thing for me not to do and causes me a whole lot of stress.
