I see . . . those are definitely challenges, but nothing that can't be fixed . . . really, what you need more than anything is confidence . . .
I remember the whole binge-eating scenario from other threads . . . you really need to control that, man . . . that's the root of all your problems
when you get the urge to binge eat, do something active; whatever you have to do to NOT binge eat . . . . it's all about controlling your impulses . . .
as you start to become increasingly active, you will start to feel better physically, emotionally, psychologically, and this will (or should hopefully) start to curb your nervousness around females . . .
another thing you have to start doing is talking to females; not even tryint to date or sleep with them, but just TALK to them . . . try to start up convos about interesting stuff . . . whether it be current events, comics, whatever . . . those are the first steps you need to take . . .
