有苦难言

Sometimes, I just want to speak up. I have things that I want to tell others. But every time I tried to speak up, I would be afraid. Like:

1. I don't know how to phrase my words.
2. I'm afraid of the change in perspective in the people I want to talk to.
3. Although they are like "Hey I'm always here for you", I still hesitate to tell them what's on my mind. I don't want to add on to their troubles.
4. I don't have 100% trust in them.

Am I the only one feeling that way?
