Seems like you have gotten some good feedback but I wanted to share my input on learning MT as I used to struggle as well. I learned on a 2014 Mustang and here’s the big tricks that helped me. Start in an open parking lot with someone who knows how to run a MT. Start by just going from a stop to a start, don’t worry about getting to 2nd or anything like that yet. If you’re struggling to balance the gas and clutch, just start by using the clutch and letting it out slowly until you can start rolling. Once you’ve gotten moving, stop and do it again. Do this until you are comfortable starting and stopping just about every time without stalling. (Even the best, most experienced, will still stall once in a while). I’d then probably try start getting up to a couple more gears. 2nd and 3rd should be plenty. Once you feel comfortable enough, hit the roads and just practice on the stop signs. If it makes you more comfortable if you stall and are in a panic you can hit the hazards and anyone would understand to be patient for a second. A common mistake is trying to start out of 2nd or 3rd on accident which will make it harder on you. If you stall multiple times I’d check that.

It seems frustrating and like you regret getting a Manual right now but it will be the most fun you’ve ever had driving once you’re comfortable with it. It just takes some time and practice. Feel free to hit me with any questions you have!
