I'm a needy person. How can I stop?

As much as I hate this, I’ve finally come to grasps with the fact that I am so goddamn needy. I always seem to need people’s affection: immediately. This affects both platonic and romantic situations, as well as work. With platonic, it’s slightly better because I’ve known most of my friends for a large chunk of my life, but I still get miffed by phone-calls not returned, texts not replied to, etc. Then, when it comes to men, I have zero tolerance for ducking phone calls, missing texts, etc.

I wouldn’t post about this if I didn’t think that its been tainting my days – it’s literally screwing with my daily life. I can’t afford a therapist right now, which I know is a mature avenue to go down, so on that issue I’m stuck. That leads to the word “mature.” I feel like a little lost boy. I am going for my 3 month visit to my psychiatrist tonight, but I feel this is more emotional and not treatable by medication. I hate being this way… it’s impacting my life. Does anyone have any tactics to fight this awful feeling?
