share more of myself with others

Nobody else does. I’d like to be appreciated, i’d like to be able to help more than just a few people out; but i just have a problem putting myself out there. It was a rough past two years, i drew inward some and lost the ability to really share myself with another. Unless somebody asks me a direct question, i’m not one to offer information… i mean, who cares right?? I feel that the closeness and affection i feel is lacking is directly related to my inability to share how i really feel, think, and desire. But how to breakout??
