Advice... Struggling

All advice is welcome, I appreciate any and all insight.

I'm not sure what to do. I feel very confused and frustrated right now. I'm struggling to make any progress in my life, because I'm unable to make a decision. I'm about to graduate as an undergrad and I applied to enter a Leveling program. At first I was excited I even got in, it was a relief. That was until I went to the advising session. At the advising session they told me my undergrad GPA (3.27) was to low to be considered into the graduate program, even if i do well in Leveling. I didn't know what to do! There aren't a lot of jobs for SLPAs in this area and I knew I didn't want to Master in something else. I searched for programs nationally, but they are all competitive.

I was thinking of delaying my graduation as an undergrad to re-take classes and boost my GPA. At my school if I re-take the same class it will completely replace the old grade. So I could go from a 3.27 to 3.52. That's assuming I make all As, but I understand how to study now so that shouldn't be a problem. The problem is time and money. My family financially supports me right now, but they think that improving GPA before entering the leveling program is a waste of time and resources. They would not support me in this choice. I don't mind taking out a loan, but only if I know its worth it. Other people have told me that grad schools look more at how I do in the Leveling program than unrelated classes from my undergrad. I've also heard that GRE holds a lot more weight than GPA. I'm in a difficult place right now, because I know once I decide the decision can't be reversed. If I graduate now my undergrad GPA will never change, but if I delay graduation I'll have to wait another year to enter the Leveling program. Do you think I have a good chance of entering a grad program somewhere in the U.S with a mediocre undergrad GPA, good post-bac GPA, good GRE scores and good LORs? Or should I improve my undergrad GPA before its too late? I should add that I work in a place that a vital stim SLP visits, and she said I could shadow her if I needed hours. If my end goal is grad school, what do you think I should do? What was your experience? Thank you so much if you read all the way to this point. As I've said I appreciate any and all advice, and am open to making difficult choices if i have to. (moving, delaying graduation, cost expense) What would you do?
