(Late response is late, I know.)
After a few days of thinking, I have read the responses on this thread and did a little more research. Thanks y'all. I feel so much better and I do plan on HRT. As much as I hate needles, I am kind of excited for it actually (at least for the positive changes), and I do plan on discussing it with my psychiatrist.
My current plan is to stay on it for 5 years (10 at maximum, it's do-able but definitely not preferred), but that completely depends on how much T affects my body. So the time on T will change in the future. But overall, it definitely is worth it.
I didn't mention this earlier, but I don't plan on getting bottom surgery. I don't really feel any dysphoria in regards to the lower half of my body, so I don't feel the need on changing it. So, pretty much everything is staying except my breasts (which I do have negative feelings about).
Again, thank you all so much. I did feel better after reading the comments. I'm just really bad and forgetful with replying.
