Bought Maxgrowth Enhanced few yrs ago. Now looking at it, realised that the guaranteed sum is actually lesser than what I paid in total? Can anyone give me advice?

Bought from OCBC, Great eastern endowment. Matured in 2027. Will pay 35k in all, but realised that sum assured is only 31k. I was looking at the guaranteed value if I were to surrender now, and is only 35% of what I paid so far, so don't think surrender is an option. If I were to wait till 2027, if year 2027 is a poor economy year, does it mean I have high chance of getting much less than what paid? Even if is good economy, does that mean that I will lose money should the investment turned wrong?
