How to deal with a sweet but extremely noisy coworker?

I really need advice on what to do with her… But in a way that doesn't hurt her feelings she is the sweetest person (she is really close with EVERYBODY nobody ever gets mad at her and she is so sensitive)

I'm so grateful for her help when I first joined the hospital. I was an outcast because I came from a very good university and my boss was so happy(kept mentioning it in front of the others ) to have me which made all the coworkers to avoid talking to me and ignore me… This lady was the ONLY person who was nice to me I can't forget that.

i'm in my early 20s she is in her 40s… And she LOVES DETAILS
she asks me about EVERYTHING where i'm going to vacation? With who? Who is paying? Where i'm staying? How much did I spend?
any topic I talk to she starts asing me questions to the point that I don't sit with her as much as before
one time I called her to ask about the direction of an evening dresses shop… The next day she is asking me what did you get? For how much? Who went with you? Did they get a dress too? Show me pictures
and when I give her my iphone she scrolls in my pictures and I don't like that

all that was ok-ish with me… But I'm ONLY comfortable with her… The rest of my coworkers I don't like them so much… And because she is VERY close with EVERYBODY she talks about my business with them and I discover they know EVERYTHING about me without talking to me

I don't have any "secrets" but honestly I feel so stressed when she integrate me like that

I had a colleague like that -- same age gap -- she is who she is… And is not likely to change -- even if you share with her your concerns -- that age difference is a factor -- you will never be old enough to offer wisdom -- correction is out -- so you have to decide today… What you will tolerate and then you will have to gradually tell her less and less of your business -- hearing less about your world will send her into SHOCK --- she will notice your precaution with her immediately -- if you ask her a question be prepared to hear it again at work -- consider another resource -- Some folk thrive on the details of the lives of others. We called it being nosy back in my day. Best wishes -- this intervention is do-able!

Sounds like she should have been a newspaper reporter! They're trained to ask Who, What, When, Where, Why, and How, get the whole story, and put it all together in an article.

My suggestion: Think of various ways to re-direct the conversation to some of her own activities. "Where did you spend YOUR last vacation? Did you have fun? What did you like doing?" You're allowed a little white lie once in a while, too: "They had some lovely things, but I'm still looking for just the right dress."

It's particularly rude of her to ask about money matters, such as "Who's paying?" "How much did you spend?" and so on. Evasive replies are required here: "We each paid for ourselves"; "It was more expensive than I thought it would be, but I had enough with me."

Don't show her your iPhone pictures. You can claim you didn't take any. If possible, set your phone so a password is necessary.

A final thought: Don't be taken in by her "sweetness" and her "sensitivity". She has cultivated those attributes so that she can get people to spill their most personal thoughts and activities to her.

By this time, your co-workers have had time to see your true nature and the quality of your work. If they get all their information about you from Nosy Nancy, it probably comes out slanted. One at a time, be more cordial to the others, and be sure not to talk about highly personal matters, either yours or theirs.
