Sorry to hear that, comrade. This is not, I repeat, not a replacement for seeing a doctor but while you work on getting insured, you might try drinking hibiscus tea. There has been some indication that it might lower blood pressure. A friend of mine was kind of on the cusp of needing to go on meds, and his doctor told him to make the life changes you've already mentioned, drink hibiscus tea, and come back to see how he was doing. It actually worked for him, but there's no saying whether the tea actually did much for him.
