Skinning animals while they are still alive is barbaric. Period. There is no real need to do it.
If you canīt kill, gut and dress an animal this is a weakness that needs to be dealt with before you are in a survival situation.
You could try and find someone to show the howtos in real life. Before you attempt to do so you may have to work on your mindset. You could also aquire the skills to procure food that isn't beyond your psycological limits. The latter may be the way to go for you.
For short time survival some people doubt that food is that important after all.
