Can't proceed in Blades quest due to glitch

[Hells_Ego]

Alright so long before i started with the missions i explored the map by going around the world once or twice and i stopped in tel fyr and went down to the bowels and killed a few of the corpeus stalkers right, it didn't give me any destryoed main quest messages so i figured i was fine despite the warnings of the people in the tower. So now i'm on the blades quest where i must heal myself from mr. fyr whos in his tower and since i killed the corpeus guys early the only thing he'll say to me is get lost you killed inmates and then all i get is the good bye option. So i can't continue on with the blades quest.

Now what i need to know is there any way around this or can i get healed elsewhere or possibly find the potion hes supposed to give me somewhere else in the world, its not on him cause i killed him once to check and he didn't have it.

You can use a charm spell to bring his disposition up high, then talk to him and bribe him.

However, if you killed Yagram Bagarn or any of his daughters, you are screwed.

nah i didn't kill anyone important like that just corpeus guys, unfortunetely his diposition doesn't matter, i sued 8 bug masks to bring my personality up to 200 and all it does it make him like me a bit more when he tells me to get lost.

If disposition does help you can always try a fortify intell potion, make a better fortify intell potion with your now higher intell and keep this up untill you can make a monstrous potion, then create a fortify personality potion.
Otherwise you'll need to use the console commands to fix this part of the quest -> ask someone better equiped with knowledge about that.
