I don't think what you're feeling is far from normal. You haven't seen her in awhile, and you're disappointed that she couldn't make it! Who WOULDN'T be upset? And when you're already insecure and have abandonment issues, that only serves to heighten them when she calls to say she can't make it.
I too don't have many friends. In fact, I have only one REAL friend -- and right now she's on life support and is in critical condition. I'm really upset both for her and her family, but for me too! Isn't that selfish?!! I'm afraid of losing her! She's been my one true friend since I was 4 yrs old, and I'm 63 now!!!
But I don't think you're going overboard in your emotions. I don't think it's addictive or manipulative. I think you're just disappointed. It's a shame that it keeps falling thru when you arrange a get-together but I'm sure it will work out one of these days.

She won't ALWAYS have to work overtime.
I know it's tough not to have more friends in your life. You can try to meet people in Libraries, coffee shops, stores, etc. Even laundromats are good places to meet people! Give it a try.
Best of luck Hezaa, and God bless. Hugs, Lee
