I have just maybe mess up... long rant

Some yrs ago i was forced to have an abortion, when i found out about that pregnancy it was so shocking that my anxiety was SOOOO high I couldn't even eat cause i was nauseous from it. Time forward now, i thought i was ready to deal with a pregnancy, but now that I'm in the position if i might be, I'm stressing soooo much, it's like having flashbacks to the time i panicked when i got pregnant. On top of that i have anxiety disorder which comes with stomach problems with nausea being the #1 thing. Now I'm not sure if I'm being paranoid & provoking myself the nausea because of how anxious & stressed I'm being or if it could mean I'm pregnant ? I keep trying to notice if my boobs are getting sore since in that pregnancy they actually hurt but now i have no symptoms at all but the nausea that I'm not sure where is coming from & it makes me want to literally cry because it's overwhelming & I'm the biggest baby when it comes to that... I know i should've avoided stuff & being more careful but i honestly thought i was ready, never did i expect to get panic over it. Not sure if to test or wait until AF it's actually due which is monday
