did any of you experience issues with your physical health during and after your relationship?

i recently went back to the doctor and got my blood drawn as a check up and i'm now pre-diabetic and i'm just feeling like a fucking loser. i went through some ptsd after my relationship ended and had some horrible, vivid dreams that would set the tone for my day. i've definitely neglected my health a lot but apparently stress and trauma can also affect blood sugar. i just hate myself that i gave him so much damn power over me.
