Hey there Greg.
I just got back to the game after 2.5 years of a relationship, so you can imagine I'm a bit rusty and have some minor (and some major) anxiety problems, just like you
Although my situation is far less complex than yours I think I can offer some tips for you to overcome the kind of anxiety and fear you have.
1. Be touchy. 90% of people find it normal to be touched (meaning, recieving pat on the back, pat on the leg, a hug, etc) Do not be afraid that people will take your touch as agressive or un pleasant. Girls, hot ones in particular are used to guys trying to put their hands all over them so believe me, they are used to that.
2. Be a hugger. Try to hug as much as possible. Huging is a sign of affection, trust and comfort. When you hug, you kinda stablish a bond of trust that's slightly stronger than shaking hands or waving (to say hello or good bye for example). Try this: next time you meet your friends, instead of just waving to say hi, or shaking hands, hug them like you hadn't seen them in months. Same applies for your family members.
3. Say hello often. Hello is a very powerful word that can help you bring people closer to you, even if you don't know them. Hello will help you being noticed more thus recieving more positive attention from friends, peers, colleagues, and people you don't (but want to) know; girls for example. A big problem with girls and guys knowing each other is that, either usually guys, out of fear or shyness do not say Hello, or, thinking they're playing it "cool" they ignore the girls, thinking that this will get them interested all of a sudden.
Hi is the first and foremost basic opener ever. Want to feel comfortable around women? Start by letting them know you exist and say Hi, Say Hi a lot

(remember to smile)
4. Seek to start small conversations with Girls you see (even if they are not Hot Babes). Might be the lady at the drugstore, or the cashier at Wallmart, a waitress at a coffee shop or an old lady at the subway; any woman will do

Ask them about the weather, about their clothes; ask them the time, directions to get somewhere, the location of a restaurant, anything... Ask them their opinion about something you have in mind (yes i know, just the thought of approaching a women can be daring but remember. HELLO is your first opener
Example, if you're at the mall and you see an old (or young) lady at the vegetables isle, say something like "Hello... Excuse me, do you think the (whatever vegetable) are ripe? I don't know much about vegetables and I want to make a (vegetable) soup today, I'm learning to cook....." THATS IT....
The idea behind this Point no.4 is just to get used to approach and talk to women as much as you can.
5. Learn to read IOIs that can indicate you when a girl is interested..
There's a good thread on IOI's around but just to sum up some of the most notorious nones:
-She touches her hair
-She stares at you
-She holds eye contact
-She wets her lips while looking at you
-She asks you things like your Bday, your Gfriend, your pennis size....erm... well, not that one haha
errmm.... (better look for that thread

)
Learning to identify those IOI's during an interaction can help you know when a girl is interested in you and how much.
6. Another advice is just Letting go. IF you meet a girl and you do not care much about her opinion about you, just let go, if you feel shes into you and you feel desire to kiss her, just go (this is where im at right now, letting go)....
