(((hug))) WHO is judging you?
Ok professionally what you are doing is called "catastrophizing"... indicated by the can't never don't nothings that you use and feel like.
But you just posted your feelings and desires very well in that post! So you DO do things right... !!!
The good news is this is learned behavior... common in your age group because we as adults have failed you in helping you learn a better lifestyle. This is especially true for the "gimme gimme right now" attitude.
You've grown up with the instant gratification of computers and technology.
You are not expected to be anyone but yourself, and you are not expected to do anything but what you can do.
We all fall into the pits if we go about COMPARING ourselves to others. God made each one of us different (and I am sure glad of that, I would not like it if there were more than one of me, or of some people I know...and I know others agree.

)
See if you can find a survey---maybe right here on PsychCentral index or homepage--- that you can take to find out what you like to do, if you like to be around people, what you're good at...for honey, we are ALL good at something!
I grew up poor but didn't know it until I had money. It was all about the attitude my parents gave the family.
I could go on about brain science and attitude and how the mind changes your environment (not just your opinion of it)... but how we can have opportunity to have what we wish ... but I won't.
One more note, when we think of accomplished people.... do you know that Einstein could only function about 4 hours a day? His brain would just shut down or cloud up or something! I learned this because due to my injury, I only get about 4-5 hours of functioning on a good day!
Start small. Work on ONE thing TODAY.. yesterday you made this great post.... now find one thing today to accomplish and then pat yourself on the back for it!
You can do this.
