You're definitely not overreacting. The bond market is risky right now, as bonds are naturally higher as interest rates are in the dirt.
This is a really awkward time to be investing if you're someone looking for fixed income. Because if you're someone who would be comfortable shifting away from bonds because of them trading at a premium, you'd naturally shift to stocks. Because again, dividend stocks are looking very attractive as rates are low.
But it can be said in that regard that stocks too are trading at a premium. So, where exactly do you turn? Difficult to say.
The typical methodology of a bond holder to avoid volatility was to simply hold the bond until maturity. However now with interest rates the lowest we've seen in a long, long time, it's very difficult to be either purchasing new bonds with extremely low interest rates, or purchasing bonds at a crazy premium and filing a big capital loss on maturity.
I'm not even sure what to tell you to be honest. Your points are all valid. Something like a GIC does not keep up with inflation right now. The best way to do so, is to invest in stocks. But I'm also not going to tell you that you should be going out and holding 100% equities, because if you're an investor who likes to add fixed income, you clearly wouldn't be comfortable with it.
One thing you could consider, and I'm not sure if you know these exist, is a floating rate bond. They tend to perform best when rates are low, and they perform even better when rates have dropped drastically. Floating rate is much like a variable mortgage, the interest on the bond will fluctuate. You'll make a lower rate now, but if your true fear is interest rates rising and devaluing your current bond, at least with a floating rate you'll benefit from the rise in interest.
Again, just a suggestion. I'm by no means a fixed income expert, as I don't spend too much time in the area being 100% equities.
