What to do as a mother?

My son graduated from college 3 months ago I paid about 1,500 a month and had all these hopes and thought he would land a job right away as a elect engineer.His student loan will strt in march so his total bills will be 900.00 .He is living a home and I downsized at wrk thinking he would be wrking.I dont know what to do?If he takes a job as a laborer somewhere he may never use his degree on what he went for.So how long do I support him in his job hunting?or do I make him take any job ?Yes his school hasnt found anything and will stop in march looking too and he has been to emp .agencys too.Thanks
