If I talk about it I'll cry, so it's a secret. (Cont'd from post below)

Does one or more idea come to mind as a secret ? You may not feel safe discussing it because you are afraid of being judged, which probably means that you do not feel that there is a trustworthy person to express your thoughts with. Now that doesn't mean that there is no one trustworthy around you , however your perspective on this is what matters the most.

You may also not discuss these thought or feelings because some information is just that personal to you and that too is perfectly ok.

If you do not have anyone to confide in, you may feel unsupported which can cause frustration, anger or sadness and those are normal emotions.

If you feel that it is important to share please consider exploring someone professionally, such as a spiritual adviser , therapist etc.
