Hi I’ve made a drawing to explain what I have. View attachment 61373
So there’s two wedge bolts anchored into the wall. I’ve got two eye nuts (yeah they’re really called that) screwed onto the bolts. The rope loops through the eye nuts and a knot makes this a triangle shape with the noose tied beneath that.
this is a wedge bolt:

This is some heavy duty equipment, I even had to buy a bigger drill. You can watch youtube videos on how to install wedge bolts. They can take a lot of weight.
I personally would not feel very secure with your setup. Do you have the ability to drill holes into your wall? Sorry you’re contemplating this method. But it’s really dangerous and you can end up with brain damage if you survive. I’d rather people are well prepared if they decide to try hanging (partial or full).
Have you tried tying a big knot at the end of your rope and just hang on the rope a bit, I mean: put your feet on the knot and hold onto the rope. See if it holds you and if it’s sturdy enough to take some extra force?
Whatever you decide; peace and good luck.
