Its very dangerous at the moment. I'd look at visiting Afghanistan and letting the Taliban know your scared of Thailand and ask if you can join them for a 6 month training camp to grow a pair.
Ive done many for my Thai wife and for friends of mine that have Thai wives and girlfriends with a 1st time approved application.
This was my wife's last application so be prepared to do some paperwork.
Be aware that you will need to provide your last 6 months bank statements that she will see when she submits the application so be sure you really want to start this application.
Also UK immigration will want to know if she has visited any other countries and also if she has been refused a visa for another country. Going through this process can open a huge can of worms, so again please make sure she is the one that you want to do this with and your not just taking her to the UK as a trophy girlfriend to show off to your mates.
The first time I took my wife (then girlfriend) to the UK she asked me if the UK has Agogo bars so me and my mates took her to a strip club. One of the strippers in there got jealous of her and threw a stiletto at her head. Not only did i feel bad for her I had a right carry on with the bouncers after i tried to launch the cow off the stage.
They miss Thai food.
They never get over the jet lag.
Its not all sail plaining so have a good think about it before you want to take her there.
