Are spiritual people allowed to have negative emotions?

For most of my life, I have been afraid to express my true emotions. I used to believe that negative emotions need to be swept under the rug and that letting go of the past meant suppressing painful emotions.
Often, when I became sad, I would only allow myself to cry in private most of the time because I did not want people to see me as a vulnerable person.I also believed that it was sinful to express anger, and spiritual people were not supposed to get upset or angry. I’ve learned that I’m not the only one. I have had clients apologize to me for expressing sadness or grief during their readings as if the universe would be terribly offended by expressions of human emotions.
However, if we don’t express our emotions but instead bottle them up, this can affect our physical and mental health. When we hide our true feelings, we are not acting from a place of integrity because we are not being honest with ourselves. Instead, it would be beneficial for us to deal with the situations or memories that brought up these emotions in the first place. Then, we can finally move on and be free. If, however, during the process of exploring your negative emotions becomes unbarable, it may be helpful to seek guidance and support from a qualified professional.
