Whatever it is you need to cut out all those damaged stems back to a healthy pair of leaves or buds as soon as possible but don't do it when frost is forecast as this can damage fresh wounds and lead to infection.
Then get down below and loosen the soil at its base with a hand fork, remove any weeds and give it a generous handful of blood, fish and bone to encourage fresh, healthy new growth. Make sure it is watered well too.

the close up of the leaves looks like a cotoneaster but it doesn't look well at all.

It looks like a plant that has been starved of nutrients for a very long time.
It looks like a cotoneaster which has suffered severe drought over a prolonged period.
Hmm looks like Loropetalum chinense with frost damaged foliage.

That's not a shrub I'm familiar with but it does look like frost damage which is unlikely to hit a cotoneaster
