Blood Pressure, upset stomach, repulsive food

From childhood I was having this problem of food coming back to mouth after finish eating by a small vomit, but I don't vomit, later as age progressed, I started getting pittam due to stress and I know the cause of it ' insecure' feeling. Be cause, currently I started my own firm, and business is very slowly picking up, this slowness, is causing that insecure feeling and I know if my business picks up well this problem of stress and anxiety will cease. This anxiety and stress is causing my bp to shoot up and causing the food to repulse. I started taking homeopathy medicine for these, for sometime, the drugs worded well, but suddenly they started to get adverse, the homeopathy doctor, has started changing drugs. Before I started taking drugs (medicine) BP was 140/80, after medication it was around 130/80, after changing drugs it was anywhere 160/100,150/90, 140/93 like that and again I started food repulsions, as I was in CGHS system till last week and after that scheme expiry, I am not taking a homeopathy as I looking for proper homeopathic doctor, so I am taking Nabicard 2.5, as once, I had severe rise in pressure, and I went to a GP, he advised me this, but I take nabicard only if it is emergency as this drug causes impotency. What I wanted to know is why after taking medicine wither homeopathy or allopathy, my problems are getting aggravated, why, is this because of changing of drugs or anxity / stress or due to allopathy medicine. please reply. I am also having severe gas formation. My age is 32.
