How do I treat subconscious stress/anxiety that makes my body ill?

Ways I know my body is stressed is by getting sick a lot, stomach aches and cramps, my skin breaking out a bunch and feeling fluttery almost all of the time. I’ve been traveling for the last 2 months and these symptoms all disappeared, now I came back to return to my life and after not even 24 hours I feel stomach cramps and sick. I believe this has something to do with the fact that I’ve been going through a lot at home in the last couple of years (including a recent breakup), so my body kind of associates this stress with this town. I dont want to move and I also dont think traveling forever is the right option, but I do get almost pissed of at how stressed my body gets by this place (stressing me even more). I know there is a lot of subconscious fear going on, which I am already targeting with therapy and medication but I want to believe that there must be a way for me to signal safety for my body. Does anybody have experience with this? What could I do? Because I’m super sick of constantly feeling physically like shit on top of dealing with mental stuff.
