Vertigo problem since last 5 months.

I am a 20 year student and i am facing vertigo problem since last 5 months and I am nor able to do my daily work . I also have c5 c6 cervical disc bulge in neck . I face regular vertigo since last months and my ent doctor has recognized it as bppv after vertigo tests . he has done epley maneuver and some advanced form of exercise too . then too my vertigo is not getting resolved. My brain's mri is also normal . I am not able to make balance , the ground seems to be lifted and there's a feel that I am falling back . the room feels shaky on concentrating on an object . I am also not able to focus correctly on objects . there's feeling of vomit but until now I have not done it . I feel a lot of dizziness at times and feel a lot of stress on my head , lightheadness etc. please guide me what should I do , is this bppv only, if yes then why is it not getting resolved . am I going to get fine someday, because I have lost all my hope due to continuous vertigo everyday.
