Are these the last days of this bass?

This is basically the last place I wanted to come for help (nothing personal guys, I am just afraid of the criticism I will get for how I handled this situation.) I am 17 first of all, so that should explain some of the following "Why...?-moments" you might have.
I got this bass guitar (ibanez srx705) 3 years ago. It was my first semi-decent bass. I upgraded from an all time favorite best bass for metal, the BC Rich Warlock. Basically a year ago I payed to have the truss rod set up and all that nice stuff. This summer I played a very large amount and then *Boom* tendonitis. So I decided to make my bass "easier to play" Under the truss rod cover I find the nut stripped, but I naturally being the eager beaver I am wanted to remove it. Then I learned about "Double-Acting truss rods". Now I don't know if this is the case for my bass, but that sure as hell would explain why the nut WOULDN'T COME OUT. lol. I took it to a different "pro" and he said the truss rod was seized. Two nights ago I took another shot at moving the truss rod. I JB welded a set screw (similar to the ones found in bridge saddles) into the stripped nut. I waited. Last night: turn... pushing very hard... *creak*. OMG IT MOVED. Pushing.... harder... *pop*. JB WELD COMES UNDONE. (I didnt set it deep enough/ let it dry long enough/ mix the epoxy correctly most likely. So immediatlely after that "success" I set another hex screw in there (thats what the picture is). It has been drying for 30-ish hours.

TL;DR What do I do? My bass is creaking and the truss rod is hard to push, but it was claimed to be "seized" by a pro.
Edit: It has become clear that I am not asking a specific question, sorry. Say that hypothetically this new "Set screw-nut" was the factory nut. What should I do about a truss rod that clearly needs to be straightened (see the picture of the action on the 4th post) but it is creaking when I go to straighten it?

 

My goal WAS to lower the action possibly, relieving the truss rod from a change in string gauge and weather, My current goal is to undo the attempt to remove the (what I suspect to be) double acting truss rod not, which resulted in an outrageous action. i cant really capture it graphically but here: (Which would also explain why I an considering this an end to my bass...): also this is where you can start criticizing me if you'd like.

 

Sorry I forgot to mention I tried multiple sized easy outs, i tried wedging a screwdriver in there, a chisel which i notched to specifically catch the truss rod nut. I did check the relief via the "capo the first fret" method. I also adjusted the bridge saddle height before hand. I am not saying this thing was in "Players condition" before I attempted to do this. It was in my 100% inexperienced opinion that I did what needed to be done. To be honest anyway. I am well aware of the mistakes that have already happened, I just want to avoid more.

 

Also, this is basically a "learning experience" for me now. I already replaced the bass, and the appraisal for a fretboard removal was more than I picked this up for (I picked it up for ($300)

 

Haha yes I am far beyond the point where I believe I can remove it. A set screw is a hex screw by the way. I can upload a better picture tomorrow. But yeah you hit the nail on the head as far as how I got it to this point. By the way a set screw is the type of screw used to adjust a standard p/j bass saddle. I am attempting to put one of these (bigger) into the whole which used to be a hex head screw via well gluing it basically. I have tested the strength by jb welding an allen wrench to a hex screw (both unrealted to the guitar) and hanging a 10 pound weight off of it which I may have a picture of and yes I uploaded it. Obviously the pressure from the torque would be different from the pressure of a (in this picture 5) pound weight suspended off of the bond.

 

Wwwwwwaaaaaay ahead of you. And I actually gain knowledge either way so it could be worth it. I have an old yamaha I could practice with, but the ibanez is neck through so idk how much different it would be. But hopefully I can get it to move and I won't have to go clothes iron my bass

 

It is neck through if that makes any difference. I guess better pictures are in order so ill stop being lazy and go take some. But yeah I have replaced this bass with a schecter studio 6 which I managed to adjust fairly well considering I have never worked with dual truss rods before. (Just so we clear this up I DO turn them both the SAME WAY, RIGHT?¡ bur as for the ibanez ill go take some pictures

 

This is a picture of the screw that I jb welded into the ex truss rod hex slot (now just a circle lol). It is about a centimeter deep in jb weld (which is in the stripped nut) and it actually kind of looks decent inside the bass. Easily accessible. The problem is getting it to stick.

 

Also this is a neck through so that is out of the question at the moment

 

Ok thanks. The concensus says to turn it right. However that in picture is not the truss rod nut, it is a screw that I jb welded into the nut. The problem is getting tepoxy to stick for me to turn it right to being with.
