I'm trying to make other trans friends

I'm trans and I am working on making other trans friends. I joined a trans club and am trying my best to talk with people.

A while ago, I talked a little with someone who is not cis and I've seen him recently at the place I work at. I was thinking I could talk with him and ask if he wanted to hang out, but I have been unsuccessful. I'm just having a lot of trouble saying anything to him.

When I see him, I don't think to say anything to get his attention. I keep thinking that next time I see him I'll say something, but I've failed at saying anything to him many times now.

I'm worried that I'm going to run out of chances to talk to him. I might have already. I don't know for sure that I am going to see him again. This is making me so sad. I know I don't know him much. I just was so excited about the possibility of having a trans friend. I want to feel connected to other trans people.
