When we are feeling vulnerable, it is quite common for feelings such as envy to arise. Vulnerability (whether due to insecurity, fear, loss, or exhaustion) makes us more sensitive to comparing ourselves with others. In those moments:
Envy can be a mirror: it does not necessarily mean that we wish ill on the other person, but rather that it reflects something we feel we are lacking or have not yet achieved.
Vulnerability amplifies emotions: when we are fragile, it is easier for what we see in others to affect us more strongly, even if in another context it would not affect us as much.
It can be a sign: envy can show us our own desires or needs that we have not yet addressed. If we use it as a guide, it can help us grow instead of blocking us.
The risk is in getting stuck there: if we don't recognize it, envy can turn into resentment or self-reproach.
The healthiest thing is usually to recognize it without judging: “I'm feeling envy because right now I feel vulnerable and it reminds me of what I want for myself.” From there, it can be transformed into motivation or self-compassion.
