Time for a new 2nd gear syncro and blocker. You've rounded the clutch teeth on the syncros and it will grind all the time now. Usually this is a result of improper clutch adjustment and power shifting. In other words, your clutch was not adjusted properly to begin with and the abuse you put it through has now caused it to round off the clutch teeth on the syncros and blocking rings. There is no fix other than a rebuild. :bigthumbsup
It's not going to hurt to continue to drive it, the grinding will just get worse.

It will take a sycro/blocker replacement as stated, that will have to be done in a shop unless you have worked on manual transmissions before. When you have the transmission taken down, make sure they completely go through it now while it is cheaper to fix everything at once. :bigthumbsup
