I wish I was better at social interactions or at least making my Asperger’s

I work in a small office so my coworkers and I are quite well acquainted owing to the close proximity of our desks. I usually arrive first in the mornings and generally get about an hour or work done on my own. By virtue of the fact that I’m an only child with high-functioning Asperger’s I generally like to sit in silence and can go almost all day without saying a word and have no problems.

The thing is, the people in my office do seem like nice people but I really struggle to force myself to speak to them and I feel like then conversations are always forced or really awkward. I wish I could mask my lack of social awareness and appear more charismatic. I think they must sometimes mistake it for rudeness but the simple fact is I can’t do small talk or proper conversations with them, I have to force it.
