I know its difficult for you, but you are going to have to train. I also know others have said your voice is quite nice as is, I dont know but I think Ill take their opinion over yours because it is quite muddled by dysphoria - regardless that means you have a very good starting point. You are just going to have to train if you want to feel better about your voice, it will probably make you feel bad because it is uncomfortable and it means focusing on a part of yourself you feel intense dysphoria about. Theres no pill for it, there is a surgery - but even the surgery for it requires some training. You've tried the technique of training a bit but stopping when you feel too uncomfortable, has that got you closer to your goals? Are you happier for it? If not, time to try something new and time to get uncomfortable (to put it lightly) and voice train. You have to start, eggnog.
The treatment for gender dysphoria is transition. You have to start transitioning socially, publically, or else it will contribute to you feeling depressed. You've tried going slowly and quite sporadically in girl mode for a year now, if you're not happy with where you are then Im going to suggest you start transitioning socially and see if thats better. You're in what is presumably a better more accepting place, now. It is time.
I know you moved and are looking for work - that part is hard, all your previous irl social life got changed and obviously money troubles suck. I think if you make a good effort to meet in real life with people you will feel better. Seek a trans support group locally, meet with them, make some friends who have a better idea what you're going through - and start going to places en femme (bring a change of clothes in a back pack if you have to). The alternative is doing what youve been doing and you've been very explicit that the status quo is not working for you and youve felt miserable. It is time, now, to start changing that.
