one thing that worked for m was to do something everyday for at least 30-60 minutes.
it didnt matter what it was or how hard you went, you just had to show up everyday. after a certain time it becomes routine and youll just go every day out of habit. but you will still hate it. thats the best i got for you.
also might wanna go somewhere else. that sexual harrasment has to be such a big de-motivator.
