Need suggestions on building a stronger portfolio. 😭

Still very new to investing and need some suggestions!

I currently have: HDFC FlexiCap Fund Quant Small Cap Fund HDFC Balanced Advantage Fund. Also, previously held Zerodha Nifty Large Midcap 250 but removed it

I’m looking to strengthen and diversify my portfolio. What other mutual funds would you suggest adding for better diversification? I am thinking an ICICI Prudential Value Discovery fund or a large cap? Also, given the current market conditions, what are the best ETFs to invest in right now? Please help a girl out, I feel like I’m really bad at this! Would love some solid advice.
