Apart from night sweats irregular, heart beat and mood swings, I'm also crying all the time at nothing. Is this a symptom also?

Yes, emotional feeling such as crying at seemingly 'nothing' is very common, it is usually caused by fluctuating hormones affecting the mood. You may find Menopause Support helpful for this as it is traditionally used to help gently raise and balance oestrogen. I would also suggest a good female multivit as well to help support the body generally at this time.
