HEHEHEHEHE, if you think think that looks bad you should have seen the first time I used a cut-throat, not a pleasant experience at all!!! I wish I had seen this place at the time as it could have saved me a lot of pain and blood. I have absolutely no experience of the equipment you are using, but it sounds like you are getting the angle wrong, it can be harder to judge on the throat area when the head is tilted back and as your cheeks are ok I would think that is where the problem is.
Leave your face and stubble alone for a couple of days at least, get plenty moisturiser on it and try again in a few days. Pick a part of the day where you can relax and take your time, even if it takes two hours. Don't bother with more than two passes and keep with the grain. Preparation is the key, get in the right frame of mind beforehand by relaxing, treat your skin, put some cool music on and spend plenty time getting the lather on with the brush, get some coffee or whatever floats your boat and let it all soak in. Get the water in the sink piping hot and go for it, slow and steady will do the trick. Rinse the blade after every pass and re-apply soap/cream where needed. After a few months of that it will all become second nature, things will speed up and get more comfortable on their own
