DO YOU GET MOOD SWINGS, IF SO HELP

Hi everyone, firstly sorry for going anon, bit ashamed of this, I seem to be getting mood swings, now this isn’t happening all the time, but one minute I’m fine, normal for me(ha ha), and the next I’m either crying or agressive, I’m a woman of a certain age, take HRT, I’ve noticed it can get worse when I’m really fatigued, could this be the MS, or just simply my BL**DY hormones, any advice would be welcomed, thanks, ANON x p.s. other than the mood swings I’m fine don’t feel low or depressed, thanks again
