That's right, some BTC are already lost forever, some BTC are going to be lost in some time. This will lead to deflation. However, the other thing that affects the possibility of deflation is adoption level. If the adoption level is high, and BTC is used everywhere, then continuous money loss will bring true deflation. And if adoption level is not so high, then the overall amount of coins probably won't affect the value of BTC.
Demand for BTC is still pretty high, so prices should be able to increase exponentially in the future. The more coins lost, the better. I don't think we'll reach a point where we'll run out of Bitcoins, since there are plenty of satoshis for everyone. If you do the math, there are quadrillions of satoshis in the 21 million BTC supply cap.
If the community decides to "recover" the lost coins, then Bitcoin's value proposition would be ruined. The only way would be to increase the supply, but that would make BTC an inflationary cryptocurrency. I'd suggest you keep buying and "hodling" as this is going to be a wild ride. Just my opinion
