Love help please.

So I’ve had so many crushes in my life. But they all seem to be with people who are taken or I can’t have. For example, 2 years ago I developed a crush on a boy in my grade that I still have a crush on today. So I asked him out and in my heard I really wanted him to say yes, but in my head I knew he would say no. And even though I knew he would say no, when he did, it hurt. It hurt so much. And tonight I was at a school movie night and I was sitting with some of my friends in the corner. So we were watching the movie and then all of a sudden, one of my friends kissed the other. And I was suppressed but sad at the same time. And they kept kissing and making out throughout the movie and I just wanted to cry. Like I really wanted to be in my friends shoes. I wanted the other one to kiss me so bad. (I’m

Bisexual btw). So my two friends who are girls are kissing and all I can think about is how I wish I was the one she was kissing. And I’ve had a lot of other crushes. I had one on a guy my friend was dating, one on a guy my much hotter friend also had a crush on (you can guess who he picked) and so many more. Whenever I get the chance to make something happen. I chicken out. I’m just wondering why I never have crushes on people I can have and why I always chicken out when I have the chance to start something. Please comment help.
