The tie in between Over eating, compulsive shopping and internet surfing

What do all of these activities have in common?  They're mind numbing and ultimately self destructive.  Passive.  Symptoms of underlying issues.  Waste of time.  Gross.  I hate myself for doing any and all of them.  Okay-clearly I'm not alone here.  They're all addictive-type behaviors covering up all kind of dreck underneath.  Instead of being self loathing-because that just leads to more numbing, masking and other "time wasters" though, I need to look at what's going on that is leading me to these .  .  .  That whole belonging/social anxiety/feeling left out: those are my Achilles heel.  And I just get frustrated because even though I "know" this, I still get stuck here over and over again-and I need to do work my thoughts.  I don't need to rehash why-and I think I get caught up in that which, while not pointless, doesn't change anything.  For the last time: the whys are shy/sensitive kid/not much money in an affluent area/parents who grew up blue collar and have their own insecurities/overweight so clothing issues/not much money as a kid so clothing issues/not athletic/super self conscious/bullied/weird social issues in high school/college with a bunch of rich kids that I didn't fit in with/clothing binges once I started working/Baltimore awful social scene/now OPE with those super thin, wealthy, socially connected women.  And all the weird little things that pop up:  the book club at the country club with smart, rich women I don't know, the kids' birthday parties with the younger, hipper, sort of snooty women (they just talk to each other and have really cute, hip clothes and look like they spend hours at barre class)  who I don't click with, the havurah drama (which is crazy since most of those people I don't connect with or particularly like anyway), having to make small talk if I'm going to be at an event with a lot of people I don't know.  Even the kids' things that send me spinning are due to my hot button issues (I worry when it appears that they're having social issues). O-kay.  Moving forward.  I can't change my past-it is what it is.  What I know about myself:  I have issues with belonging, feeling left out, feeling judged for how I look and what I have, so money/body/social occasions are hot buttons for me.  And I've vacillated between avoiding things so that I don't feel vulnerable, and getting out there and then feeling (occasionally) yucky.  I need to just check in every day and recognize it when it's happening so I can change my thoughts about that specific thing.  And just saying-ah, yes, hello hot button issue.  Which I feel like I need some catchy name but I'm so tired at this moment on New Year's Day that I can't  think of any!
