94 Sentra, worth fixing or sell?

I bought a cheap 94 Nissan Sentra SE 2 door
automatic. Cheap in more than just price. I was in
a desperate situation and got ripped off.
It gets me to where I'm going, but always have the
fear that it will kick the bucket at any moment. It
needs a lot of repairs.
Just to name a few:
Trunk damaged and doesn't close, water gets in
Damaged tailight
Glovebox door fell off
Driver side door doesn't open
No a/c
No headliner
Runs Really rough when idling, sometimes stalls
Have trouble telling which drive gear its in
Sometimes stalls when starting to drive or
reversing
Has 288,000 miles
I'm sure there are more things wrong with the
engine, it looks horrible and I just don't know
enough about cars
I need a more reliable car. Can anyone give me
advice whether I should fix it up, or better to sell it
as a whole or for parts? I haven't registered it yet
as I a still trying to come to a decision. I can
provide pictures if needed.
