Suggest Treatment For High BP Despite Taking Lisinopril

I am a 31 year old female that has somewhat good health. About 2 years ago I started with a really bad headache that would not go away that sent me to the er a couple times. It was discovered I had high blood pressure, sometimes as high as 170/120. It was also discovered that I had protein in my urine and after a 24 hour urine test it came back 5x the amount it should have been. I was sent to a nephrologist who did blood work and a kidney biopsy who has diagnosed me with FSGS. About a month after this diagnosis I got pneumonia and was hospitalized because my O2 dropped to 84 while I was walking. Every since this, I get really short of breath, my lips will turn blue and I will feel like I am going to pass out. I have had 2 D Dimer test done. The first was .94 and the 2nd was 1.91. They ruled out PE. I have CRP done 2x. The first was 13.4 and the 2nd 21.8. They have yet to find out why. I have been to a pulmonologist who did PFT and says everything is normal. I have seen infectious disease, cardiology, my nephrologist, hematology/oncology and the only thing that anybody can find is that my hear rate was high. It got into 180 s without me even knowing it when I was wearing the heart monitor. I take my birth control pills, 100mg Zoloft, 40mg lisinopril, 20mg Prilosec, and 75mg toporol XL daily. I still have a little bit of trouble with my BP and heart rate on occasion and none of the other symptoms have got better. There is no common factor that makes them happen. I can be sitting at my desk or walking. Any recommendations or suggestions are greatly appreciated.
