My little sister is 4 years younger than me. She has a wonderful life. Our mother is quite liberal and lets us do whatever we want, providing its within certain boundaries (no drinking under-age, no drugs, no sex under-age, be a nice person, don't lie/cheat/steal etc etc)
My sister has a very active lifestyle, just now I helped her pack for a night out with her friends. They are going to a battle of the bands. They were excited about going, with all of their friends.
I'm happy that my sister is happy and healthy and enjoys things in her life.
The problem is I'm the opposite. I'm not happy and healthy, nor do I enjoy life.
Until recently, I was just like her. Even more outgoing, I'd go to clubs with my friends, drink and spend time with my boyfriend. I had a job, I had money and I had my education (the most important thing to me) That all changed.
I can now go for weeks without my phone ringing and even when it does, it's either my mum, dad, sister or my doctors. I don't even both going on social networking sites because most of my so called friends have deleted me from not just their virtual online lives but their real life lives too. I have been deleted completely. Sometimes, I hear people thought I'd dead. They didn't even bother to see if I had died or not. I do think that if I had died, my funeral would be a very empty one.
It's hard seeing my sister be outgoing and have so many friends. I want that. I had that. I lost that.
How do I get over it? How to I even begin to come to terms with the fact that no one cares whether I'm alive or dead?
I'm 18 years old and I have no one in this world. I'm very very lonely.

I'm really sorry that everything turned sour for you, poppyfields. It's hard to see someone else enjoying the life we had once. I feel that true friends stick by you no matter what or at least try to patch things up when it all goes haywire.
It's natural that you should feel jealous of your sister, but don't let it eat you away. Try to tell yourself that this could be a new beginning, that from here on, you will rebuild your life and bounce back better than ever. Take inspiration from your sister if you can. I know you can do this. It may sound difficult, but you'll always find help here if you need it.
Hope you feel better soon.
