During those first three "good" months I had, there was no shvua.
Wait a minute. You are starting there? What about the three yeas before that? History is everything when starting out in this business. So: when did the problem first start, and how often did you resort to masturbating yourself and/or to using porn, for how long and how often, and what other behaviors besides looking at pictures or sex with yourself did you get into the habit of doing during that period before you came to GYE please? As ppl here have said, people need different tools - so lets get as much of the situation right out there rather than hide details. It will help you and everyone who does it.
I was in a happy place and I was almost always busy so I was ok.
That's great!
Then after the next 2 months were terrible
what does 'terrible' actually mean? Exactly what were you actually ,doing that made you call it terrible and how often, etc (as above)?
I decided that I gotta do the shvua or I may just stay in this rut,
Do you consider the 'rut' just behaviors that if they stop then all's fine...or do you see that if you, being a good yeshivah guy (you are), were habitually resorting to lust adventures of some kind (stuff you gotta to hide!), that there must be something amiss with the way you are functioning? Not that you are bad or psychotic, c'v, but that you are just missing something? For you surely want to be good. In other words, if the only thing you really needed to do was to stop these behaviors you call the 'rut' and a shvua would work, then why do you not simply just do a shvua again as soon as the old one ends immediately, and on and on?
You said it might explode. Good point.
So do you start to see that even with a shvua that would work 100%, you cannot escape and will still have to change inside in some way? And that you cannot possibly do that yourself or you'd have done it years ago?!
...and it helped. I can't say there weren't tough days, but never to the point where I would break it, simply because it wasn't worth the big knas to me (which I made for 300 dollars) then after it was over I was willing to fight with myself but for wtvr reason my internet was unlocked and so coming off 3 good weeks it was to tough of a fight and so...
So...what?
and I haven't made the shvua since which ended about a week ago bec it may keep me sober but I don't know if its kedai cause I may just have an insane binge when it ends.

Insane? If you feel it is insane, why are you playing around with shvuas? Would you suggest anybody else with a problem that leads him to do terrible things to just do a shvua about it"? Or would you suggest they take it a little more seriously than just a bad habit or 'aveira', and go to a shrink? Have you considered seeing a good counselor or psychologist over this? Or is not important or serious enough?
which comes back to our previous point of just pushing off the inevitable... what do u think I should do?
P.s. not sure i understood ur question so I thought this is what u wanted to know but if not lemme know

This post was extraordinary in the brutal honesty and introspection that we all need in successfully confronting our addictions.
