Real Analysis as a JR SUCKS. PLZ HELP

I am currently taking Real Analysis (undergraduate) as a Junior, and I have absolutely no idea what’s going on. I was told that ideally I would taking this class a YEAR FROM NOW.

I have had so many mental breakdowns and I am just at my wits end and would appreciate any advice on good places to get help, YouTube channels (maybe?!?), or any specific on advice on the content itself.

I suppose this is also a PSA to NOT take Reala analysis as a junior if you have the option not to, lol.
