Four month always unhappy

My son just wrong for months in about two weeks ago he just started these really weird faces were all he does is fuss and cry all day long he smiles he does not live he does not want to roll over I don’t know what to do I find myself crying over and over sometimes and I feel like I just can’t help him he has acid reflux but we’ve had it under control he just seem so unhappy all the time I can’t get him to take naps so he’s just so unhappy all the time and I just don’t want to do anymore
