Hi Sami - sorry to hear about your loss. I cannot imagine what you must be going through.
I find that when I embark on a new healthy regime I get a breakout. Not sure if it's to do with sweating more because you are exercising but I would advise just to keep doing what you're doing, wash your face after exercise and am/pm (not excessively as this could make it worse) and maybe try and get a bit more sun? If I get a spot I find a dab of sudocrem before bed and by morning it's nearly gone! Even though you may be tempted - don't pick them! Not sure if this helps at all but thought I'd make a suggestion albeit probably not the one you were after.
