I realise this might not be the same thing, but I once had a girlfriend who was very similar to you.
Basically, she was completely obsessed with getting attention and affection from me, and pretty much anybody she could get to be around her. She'd keep me up for hours into the dead of night, when really I'd have to go to school the next day. She never had anything worthwhile to say, and when she texted me it was usually some vapid shit like "Mrow" or "I love you.", and it got FUCKING INFURIATING.
Now, her problem was much the same as yours. She had abandonment-issues and she was deathly afraid that I'd stop loving her - which is ironic, as her constant doting was the exact reason I stopped loving her.
I know that you want affection, and you're afraid that people will stop talking to you, but believe me when I say that it doesn't matter. Even the most patient person in the world will get tired of overly clingy people eventually. It makes them feel bad, it stresses them out and makes them tired/annoyed.
So try to control yourself. Something I tend to do when I have somebody I really like talking to, and I feel that I'm being too clingy; I try to have a point with sending the message. Wether it's a personal question or something that you feel that you actually need to know. Look at the question and ask yourself "Is this important?". If it's not, scrap it and wait for another question to come to mind. In the meantime, the person you want to talk to might come to you.
