I am viewing ur trading details first time. As a trader, I can understand some inside details..
F&O has min lot size which is big for individual stocks. So the big loss using F&O was due to the highly leveraged position with small capital which was not adequate for F&O trading.
Overtrading or Revenge trading is another part.
Trading is a mind game, many time whenever an intraday equity trader suddenly face loss after a series of win, he/she try to cover using more leverage, shift to F&O. That point due to big lot size and less capital u can't make average entry or book partially like before. U started neglecting your own money management rule unintentionally, that was the reason for such one-day big loss using F&O.
If u think in details, u'll know F&O was not the culprit but not following ur own style of money management(partial entry and partial exit etc).
And knowingly or unknowingly u r following the basic pyramid trading strategies so if u go through several tuto about it u'll be benefited soon IMO. U can fine-tuning ur SL and EXIT using pyramid money management along with ur charts...U r following it unknowingly...
Just take care of position sizing and money management. Stick to your plan..partial repeated entry etc... Wish u lots of profit soon.
