I would say leave it to a mechanic you trust. Pulling the engine out is actually not that hard, it's taking the gearbox apart and making sure all is prim and proper when you put it back together again that's the difficult part. At least for me. I've seen it done and if you want to do it yourself maybe write down a motivational on a post it and put it up in the garage. Like "I will not lose my sh*t today over this" or something.
