The first card you look at is The Tower. This major arcanum represents a profound and sudden change in life, bringing with it a moment of reflection and introspection. It invites us to look at the situation from a broader perspective, to reflect on our personal experience and to make the most appropriate decisions. In the case of the question, this card suggests that we think about what Marisa's camera means to us: if it represented something special in our lives.

The second tarot is the reversed Ace of Cups. The Ace of Cups symbolizes the feelings, emotions, love and passions we have for something or someone. Reversed, it can indicate that we have turned off our feelings, that we are unable to appeal to our emotions, or that we have difficulty expressing our feelings towards something or someone. So, in the context of the question, this card could suggest that Marisa has a special place in your heart but you are unable to express it.

The last tarot is Justice. The Strength represents your inner will and your courage to make difficult decisions. As a card, it reminds you to act wisely and responsibly when making important decisions and encourages you to remain calm even during times of stress. In the context of the question, this card suggests that we be aware of our possibilities and limitations and be wise in choosing the best solution.

In conclusion, considering all the information provided by the three cards, it seems that you need to consider what Marisa's camera means to you and how you can express your feelings towards her before making a final decision. While your emotions may be confusing, you still need to be wise in your actions and avoid hasty or rash decisions. Considering all of this, it seems more reasonable to keep the camera as a keepsake than to keep as a keepsake than to sell because it would mean a lot to you in the future.
