I'm with Jamil20: but first, check these things:
Is the grab rail handle still there on the left side, bolted to the shock and frame? If not, maybe find one and put it back on: these were often removed to install saddlebag and luggage racks, then got lost. It's in the perfect spot for the straight-up right-leg+right arm lift. I also pull back on the left handlebar, or put my left hand under the seat edge near the front, to help. It's real difficult to do with a 200+ lb touring load aboard!
What size rear tire do you have? With a 120/90 x 18 rear tire, it is easier than with, say, a 110/90 or 4.00 x 18 tire.
Where are the shocks set, and are they stock shocks? If they are shorter than stock (or K0 shocks, which were shorter), or if you have a lowering kit, or smaller-than-18" rear wheel, the lift is a considerably longer distance and the startup is at the wrong angle.
Years ago, there was a fold-down chrome footpiece with a clamp that grabbed the left side of the stand, and it would lay out flat behind the stand when it was first lowered. You would first sidestand the bike, then lower the c-stand with your toe, and flip the footpiece over the crooked arm that wraps the muffler when up. If you let it go at this point and it slapped upward, it dented the bottom of the #2 pipe, but a gentle release was OK. Then you would line up for the pull, straighten the bike, and the footpiece gave a much larger foot push area to work against.
My secret has always been to wear thick-soled boots when I ride, partially for this purpose...
I still stand the bike every night, because a couple of times I have seen little neighborhood kids climb up on it. Once I found it lying on its side (from the sidestand), making me wonder if someone got hurt if it fell on them. It sure didn't help the cases out, either.
