I can't say what is going to work for you. I have been on HRT for 11 months, and full-time RLE for 8 months. The difference between before and now is amazing - no comparison.
There are still things that make me dysphoric. The need to wear a wig, for example, though it is not nearly as bad as the dysphoria I would get if I didn't wear one. The need to tuck when wearing pants. The long delay I face before I can get my birth certificate changed.
That stuff sucks, but it all pales in comparison to the high I get from just being myself. Not having to hide who I am is just the greatest feeling in the world.
If you are wondering whether HRT will be worth it, it certainly was for me. I am calmer, with less mental static. I am more relaxed in social settings, though I'm not sure how much of that is HRT and how much is just self-confidence. The physical changes have been amazing, even though they are kind of under-stated. I have breasts that, with a padded bra, give me a plausible figure. Tucking is way easier. And the changes in my face actually have me admiring myself in the mirror.
I am sure your therapist is helping you with this decision, but ultimately, it is yours to make.
