Layers

I am the type of person that doesn't show all of me, the raw me until I'm comfortable enough. I have a hard time showing when I'm sad or upset because like 'Shrek' says 'i m like an onion with many layers. I don't always reveal all layers until I feel that person can be accepting of me and be there for me. I reach out very rarely and in very small baby steps, but if if on my first small step I am denied its like the first layer suddenly appears and its tough to break through again to the layers I've already exposed. When I reach out it may not be not appear so obvious but if I try twice to reach out and say I'm upset and one ignores it, its a big red flag to me. Deep down I'm emotional, passionate and at times just want someone to listen or even hold me and cry because sometimes i hold it in so much it feels good to be passionate and emotional. I can truly say I have this with my best friend , she is the only person who has ever seen all my layers and I like to think this is why we love each other so much. I see her and she sees me, and that's enough. But she isn't always around and sometimes we need our space so I reach out to someone I thought was ready to see more of me, discover another layer to me, but nothing. Now where do I go from here? How do I proceed with someone that didn't want to hear me be upset or talk it out , someone just to listen. Instead I get nothing and I'm at a loss for words.
