The tree IS about 25-30 feet tall.

==>>> the tree WAS such .. it isnt any more ...

prune all broken stuff back ... and give it some years to recover ...

but your bottom line is.. it will never be what it was ... its on to something new .. which you can guide with future pruning ...

if you cant accept that it has changed get rid of it .. but that is more change.. lol .. vicious circle ...

with not insult to the root mass... you might be surprised how fast and how vigorously it comes back .. and i am talking in tree/shrub time.. not our world of instant gratification ...

there is no reason it should die ... just because of what you describe...

I second Ken's statements and will add my Crepes die to the ground near every winter and come back with vigor.

CrApe myrtles can be cut back to ground level and regrown. If they have a healthy root system, they'll grow back very quickly. Chances of them growing back are about 99.999%.

You will have to decide how many trunks you want to regrow and remove all the rest of the shoots before they get too big. I strongly recommend snapping the new shoots off at their base before they get so large that they have to be cut off. Shoots that are cut, rather than pushed/snapped off, will tend to grow back. Even the ones that are pushed off may lead to some regrowth, but it's noticeably less that when shoots are cut back.

You will also likely have to tie the new trunks up for a while to encourage good straight growth. I have had good luck with using old pantyhose for that purpose. Usually you can just tie opposing trunks together without even having to use stakes.
