You'll probably need some special tools - or take it to a bike shop and let them deal with it.

There is no quick fix, you need
new chain and gears
new brake lines
new brake pads
to stay safe

There may be some chain links that do not move freely. turn the pedal slowly backwards and check for siezed links, as it goes through the deraileur.

A worn chain can do this as well, unfortunately you usually have to change the chain and sprocket cluster as a pair. If you just put a new chain on a similar problem can occur.
