losing friends

my dad is in the military so ive always had to move around and ive lost a lot of friends from that. but i think its more due to that i get so nervous that when someone doesnt text me that i dont text them to see what happened. its fear that ill be rejected and i havent kept friendships for longer then 2 years. i lost a friend cause we lost contact, she was always there even when i didnt think she was. i miss her a lot but i dont have a phone anymore so i cant talk to her. she didnt tell me a lot of things and i know that i was just a waste cause shes had friends since she was kindergarden.
