Q: engine struggles turning over and rpm don't move from 0

It sounds like you have both a stalling issue and difficulty starting but if the car is dying immediately after starting and you keep trying to restart it, that alone will cause the battery to discharge and explain the no start, or hard start condition. I would suggest you request a stalling diagnostic. The responding certified mechanic will first check for diagnostic trouble codes. If no codes have been stored, the mechanic will evaluate the typical causes for immediate stalling which are a faulty mass airflow sensor, faulty engine coolant temperature switch/sensor (typically at cold start only), faulty camshaft or crankshaft position sensors, worn spark plugs, wires or defective ignition coil(s), inadequate fuel delivery or pressure (clogged fuel filter, injectors, faulty fuel pump or pump circuit), contaminated or old gasoline, defective throttle position sensor, faulty idle air control valve, leaks in the EGR system, intake vacuum leaks, and so forth. If you request the engine stalling diagnostic the responding certified mechanic will get this resolved for you promptly.
