what is the cure for jealousy of others interactions

for example when i see men flirt with women or the other way around -offline and online i feel incredibly jealous about it, towards them....as i think that should be happening to me? and i clench my teeth and feel like really getting angry.......in my life i have never had a relationship because i have endured mental health problems throughout my adult life, never had a relationship at all......i had flings in my youth, but thats it.

so when i see these other people i feel like i have been personally denied and deprived of relationships and fun with women, and i think it is 'unfair' that ''that'' is happening to them, but not to me?

can anyone help with this?

maybe instead of sitting around stewing in envy you could try emulating them and create some interactions for yourself?
