How do I know if someone close to me is struggling mentally?

Hi Risabh, To read the mental or emotional state of another person astrologically, we must know their very birth details (date place and time) But, because you are asking on behalf of your beloved, we will find out what the Tarot reveals - 1. The Moon This card reads, your loved one could be concealing their real feelings. On the outside, they can appear alright but on the inside, they are perplexed, anxious, or frightened. Other times, they cannot share because they do not want to load other people down.Be kind, patient, and provide them with a safe zone. They will gradually open up when they are sure that you do not judge them. They can be cured simply by your composure. To read it properly I require details as I have indicated above.
