<human>: I've had an issue for the last few years that I don't know how to solve.

Sometimes, with new friends or friends I don't know very well, I feel severe trust and insecurity issues. This insecurity ranges from not wanting to tell them when I'm out of town, what my schedule is, details about my life, details about my love life, etc...

I'm an outgoing person, but pretty private about certain aspects of my relationship and home life with most people.

I'm not really sure where this comes from. I have a strong relationship with my boyfriend. I have a strong relationship with a handful of people.

I've maintained long term, close, trusting friendships with a small amount of people.

Thanks for your time.

I've only noticed this happening in the last few years, and mostly with new friends, specifically women. I'm having a hard time differentiating between sincere instinct and incorrect assumptions.

To those that have experienced this, what was your experience? How did/do you get through it? 

How do I move past this issue? Any suggestions on ways to gauge rationality or reasonable doubt?

Provide a brief overview of the text.
