Psychologist - Ines Sellami

Everyone feels sad. After a breakup, a loss, a professional failure, or a painful disappointment, sadness is a normal, healthy, and even necessary emotional response. But sometimes, that sadness does not pass. It settles in, deepens, and begins to affect every area of daily life. That is when many people ask themselves: am I simply sad, or am I suffering from depression?

Overthinking can feel like being trapped in an endless mental loop. You replay conversations, imagine worst case scenarios, question every decision, and struggle to switch your mind off. While reflection and self analysis can sometimes be helpful, chronic overthinking often increases anxiety, stress, indecision, emotional exhaustion, and self doubt.

Saying no should be simple. And yet, for many people, it is a source of stress, guilt, and even anxiety. We accept invitations we do not want, We do favors at the expense of our own time, We end up exhausted, wondering why we could not say no. But saying no is a psychological skill grounded in something fundamental: personal boundaries.

We often hear: “He/she is naturally good at learning” or “I was never good at school.” These beliefs are deeply rooted, yet they are misleading. Research in cognitive psychology and neuroscience is clear: learning is not a fixed ability, but a skill that can be developed with the right strategies. It is not who you are that determines your ability to learn, but how you learn.
