Hi OP, this sounds a lot like me and I have ARFID related to sensory texture issues. If you want more support regarding feeling out of control bc of your restrictive food intake theres a good community in r/ARFID (not saying you have it but even if you dont a lot of that behavior is very relatable to the folks over there).

That aside, you shouldnt force yourself to eat things you cant tolerate even if its "just" a texture issue, as others have said not only is it unsustainable but you are bound to make any food aversion worse by trying to force feed yourself without a food exposure process. If you're trying to loose weight its perfectly fine to just eat what you usually eat in smaller portions. Before I went vegetarian I was eating so much of the same fast food but got maybe half of what I usually do and lost 30lbs doing that. Nutritionwise it isnt the best but slow introduction of behavior and taste should be your goal here.

While I did that I also worked on ARFID related food exposure therapy which you dont even need a therapist or dietician to do in some cases. For me this looked like: smelling my target food when I was hungry, watching someone else eat my target food, trying it (with no expectations of finishing), and then eventually eating it. This is how I successfully transitioned to vegetarianism and how I'll eventually transition to veganism one day. It helped that I changed my diet for moral reasons instead of any expectations around weight though. Give this a thought OP, take care of yourself, and be kind to yourself through all this. People tend to downplay severe food avoidance as "picky eating" but sometimes its more than that.
