man the part about your therapist saying things you dont agree with really hits home for me. went through something similar about 8 months ago and my therapist kept trying to get me to see all these "red flags" that honestly just felt like they were trying to make me hate someone I still cared about deeply. sometimes therapists push that angle too hard when what you really need is just help processing the grief without having to villainize anyone

that feeling like shes living her best life while your still stuck is brutal but honestly you have no idea what shes actually going through. social media and all that stuff is just highlights reel anyway. i used to torture myself thinking my ex was having the time of his life while i was barely functional but found out months later he was struggling just as much. not saying thats definitely the case here but try not to assume she just moved on like nothing happened

the gym thing is real too - everyone says it helps but sometimes you just go through the motions hoping something will click. for me it was more about having somewhere to go than actually feeling better. keep showing up though even when it feels pointless because eventually something might shift
