Well... since you mentioned LGBTQ people... I thought I'd try replying to this. I'm an older man who has waged a life-long struggle with gender identity dysphoria. So I'm painfully familiar with having the inside not matching the outside, so to speak. In my case, though, there is no acceptance. It simply is what it is.

You didn't say what feelings you have that don't match what you want (or think you want.) So it's difficult to be very specific. Personally I don't believe it is possible to force your feelings & thoughts / wants to match, any more than you can force yourself not to have intrusive thoughts. (Trying to force yourself not to have intrusive thoughts is a surefire way of making certain they'll keep coming back stronger & more frequently.)

What I do, in my situation, is simply to "sit" with the sadness I carry around inside all of the time. When it stirs (which it does... a lot) I breathe into it, perhaps smile to it, & allow it to just be there until the thoughts / feelings fade of their own accord. It is a practice which is referred to as "compassionate abiding". Of course, the thoughts / feelings come back. I don't really expect they'll ever stop completely. So when they come back I simply abide compassionately with them again. Over time this practice does tend to lessen their strength as well as the frequency of their return. But perhaps more importantly, what it does is to show us that we can stay with difficult feelings & thoughts without becoming hooked... without losing our balance... our equanimity. I wish you well...
