Chain keeps slipping and I can barely peddle without it slipping over and over. It seems simple but idk
Any opinions on how to repair this?

It’s like the rear derailleur is missing the tension spring.
Rear derailleur is broken. A spring should be pulling the cage so that the lower pulley is tensioned backwards. Maybe spring snapped. Maybe the tab that holds the spring snapped. Maybe something else snapped. Won’t know without very clear video and non-shaky of the right areas showing the derailleur articulating (preferably without the chain).
Simplest solution is to replace the derailleur.
A skip
Go to Old Spokes Home to get a replacement derailleur. And while you’re at it, lube the chain.
While you don’t need this rear derailleur’s MegaRange compatibility, [the Tourney TY300 is likely available local, for $20, and will work for your needs.](https://www.universalcycles.com/shopping/product_details.php?id=88089&attribute=214172&srsltid=AfmBOoo-emGGnQ8tPxtQ7XdAs_QGodPQk0HKr7CARz5pOJ7wm_lYqsydypI).
If you’re tight for cash, the derailleur is really all you need. But you’d be well advised to get a new chain, lube, cables, housing, and brake pads.
But /u/supersensei12 is correct: This can be repaired for cheap at a co-op. Hopefully you have a bike co-op in your town, because most commercial bike shops are going to charge you more to fix that bike than it would cost to replace with something better – and if you were mechanically inclined yourself I’d have expected a better structured question and photos.
separate the derailleur from the bike and rotate the lower cage anticlockwise, should engage the spring again and would assume it’ll restore b-tension to the chain when reinstalled
