Man, you're so wrapped up in your determination to believe that you are 'nothing' that you're making it a self fulfilling prophecy. We all have times in our life where we feel just like that. The difference is whether you choose to turn your dispair into determination to change. How many guys on this thread have told you this? If you keep telling yourself "I' just can't" then lo and behold, you won't. You need to break the cycle of
self pity. It's self perpetuating.
Trying to jump in at the deep end (ie. going clubbing alone) probably isn't the best idea at this stage. You need to work on your
self image before you take any more steps into the wilderness. This is basically
your own internalised perception of what you are capable of. And more often than not it is seriously flawed by childhood experiences and whatnot. These flaws are known as cognitive distortions and can be crippling when they build up.
It is possible to remove these 'thought mistakes' and to build a more accurate self image. It's not simply 'positive thinking'. Positive thinking doesn't really work because it challanges basic beliefs without any real proof. Reassessment of cognitive distortions challanges these thought mistakes and gives you an ACCURATE self image.
Check out
http://www.youmeworks.com/ for more info on cognitive distortions. Someone mentioned Psycho Cybernetics earlier in the thread too, I
highly recommend this book. It only seems like 'sales hype' in the opening chapter then it becomes very helpful and enlightening. Even for people without significant emotional problems I would recommend this book.
Get a routine. Put your energy into something you feel passionate about. Join a gym. Or get one of your own. Work on your image. Make a point of TALKING to people. You may feel like **** at first, but if you can intellectualise the fact that IT DOESN'T AFFECT YOU what they think then it will become easier over time.
First thing you have to do. VERY IMPORTANT.
You have to change your mindset from this:
"I'm so useless. Nobody likes me. I can't do anything."
Into this:
"I am so sick of feeling like this. It's NEVER gonna change unless I do something about it! That time is now!"
And then next, don't give up. THIS IS EVEN MORE IMPORTANT.
Nietche said "the worst kind of human error is forgetting what one is trying to achieve."
When I was going through something like this, I kept a journal of what my motivations were, of my progress, of my thoughts. I wrote every positive thing I could think of in this book for a couple of months, and carried it everywhere with me. By the time I finished the book I was a lot happier and a lot more confident. Now I feel like I am reborn.
