Why does it feel like everybody but me has made progression?

Okay, So, recently 2 friendship I had ended. And it seems like both of my ex friends really could careless and has moved on with their lives. I mean, don't get me wrong, I have learned things. But, I feel like because I am no longer in their lives they`re doing much better. It's not even like I am a bad person, in fact, I am a good person. But, I tend to be immature,I care about people opinions, and sometimes give an attitude. Despite that, None of them have reached out two rekindle are friendship. Eventually, I have some what accepted that. But, I don't want to feel like I have nothing going for my self. Since, I was so dependent on them and their opinions on how to live my life. Now that they`re out of my life, I feel some what lost. Both has got a boyfriend, one has gotten a job and the other began to volunteer. Me? Nothing. Worried about others. I have nobody to turn to whenever I have a problem. It's like I am the only one in this world. I`m the one who has lost everything. People's opinions and concerns are affecting my life dreadfully..How do I get over this?Please.
