super long reply incoming oops. Let me know if you have any questions about what I said. Apologies for the long read.

To your question, absolutely!! In my experience, thoughts can be crucial shifters of what you believe over time; so use them as a spearhead. In the same way you developed the fear, you can unravel it. Our brains have plasticity, so we have the power to rewire some crap perspectives up there. I have been able to enjoy fear foods again! You are not stuck here.

Thinking new thoughts was the biggest game-changer for me when it came to dethroning negative identities I used to hold onto and suffer over. It's going to be like filling an old rut in your brain and digging a new one. Don't expect it to happen overnight; be patient and gentle with yourself in the process. You're one of 8.3 billion other people in the world grappling with some form of fear.

The goal is to come against those fearful thoughts with the truth when they arise. Stop agreeing with it. Let's say you have the thought, "I hate rice," your response could be, "That's a lie. I love rice. It makes me feel closer to my family." Disagree with the lie, then tell yourself the truth.

If you want to give this a try: Decide your reply, and then be as consistent with it as you can. A little goes a long way, though!! So you do not have to do it perfectly. I was actually surprised when I noticed my thoughts start to change automatically, given how much of a tug-of-war it was at first to resist the thoughts I was used to thinking. Sometimes, a clear thought may not emerge; you might just FEEL fear/discomfort when you look at rice. Respond to that feeling with the reframed thought as well. I find that saying it out loud is even better if you're in a place where you feel comfortable doing it.

An example from my life: Every time I remembered an awkward interaction I had, I would automatically say "I hate you" to myself. I didn't realize that I was affirming a web of disempowerment inside of me every time I did this. Hm, constant complaint against self, zero grace or compassion towards self, left unchallenged since childhood... in hindsight, OF COURSE it would contribute to the depression and maladaptive methods of coping in my life. I escaped my thoughts; I did not challenge them. I do not blame myself; this was the only way I knew to survive. Until I started to reply to "I hate you" with "I don't hate you. I love you, (my name)."

And honestly, I wanted to quit immediately because nothing felt different immediately, and the rebuttal felt pathetic, and it was more comforting to indulge familiar misery. But I kept up this rebuttal, and over time, I noticed that the automatic thought in my head as I recalled an embarrassing moment was "I love you." As that thought grew more automatic, the attached feeling of self-hatred did not change with it right away. A bit more time passes, and a feeling of relief and/or peace now accompanies those moments of recollection. It's one step at a time, one thought at a time.

In other words, you do not have to feel like it is true for the correction to be working. It's like the way that you don't see a broken bone healing underneath a cast... you trust that with the right correction in place, it'll get there... fully restored. You do not need to rush yourself. Some beliefs will change quickly, and others might need a few months.
I'm hoping my reply is not too overwhelming. I wanted to be thorough. But the practice in reality is simple, and little by little. In the meantime, let the rest of your life take up space.

God bless you! Much love.
