I feel uncool

Sometimes when I see my friends or hang out with them I feel like an uncool person who has nothing going on. 

I don't really want a boyfriend and I back in highschool to get my diploma but all of my friends (who are my age or younger) are much further than me in life. 

They have jobs, a boyfriend, an apartment. They have experimented with their looks or have a fashion sense. 

I have none of that. I don't even want a boyfriend but I still feel like a child for having nothing going on. 

I have many goals in life. I might leave my country and move somewhere else. I want a private aircraft and a cat. 

But I am scared that it will take me more than 10 years to reach these goals. 

In a week I will see a friend of mine. We haven't seen each other for over three years and now I feel insecure about my life and looks. She is very cool, has a BF and an apartment. I have none of that. Maybe in a few years I will have those things. I don't know. 

Another thing I am scared of as well is my friends getting married and having kids. Not because I am envious, but because I am scared that when they have a husband and a kid they will have no time for me. I love my friends and I love hanging out with them but whenever my straight female friends get a BF they forget me. 

It's either it's all they talk about or they suddenly forget me and stop contacting me for weeks and months. 

I respect their life. They have a job, hobbies and other friends but it is still frustrating seeing my straight female friends forgetting about me completely. 

All their energy suddenly starts to flow into their boyfriends. 

One former friend of mine broke contact with all of her friends so she could concentrate on her BF. Which was complete bullshit. Months later she called me crying to tell me that she broke up with him and is now lonely. 

I couldn't be friends with her anyone. This was one reason but there are thousand other reasons. 

Does anyone relate?
