I think I have plenty of love - or at least tolerance of myself - mentally. I believe that what is "me" is in my head, my thoughts, personality, perceptions. The body to me is more like a mobility suit. I get along just fine with myself - in my head - in that sense and I don't fight or blame myself there.
My body is to me more just a bag of meat and bones that I cannot really control. It's my flesh prison and if something happens to it, I go too. I've never been able to "love" or "like " my body, because I can't control it at all... it does its job, tries to do female things like bleed and flood itself with hormones back and forth and store fat, but I do try to look after it because without it I'm screwed. I used to actually hate it, but for some reason I've never been able to harm it myself, despite how much I hated it.
I don't think you necessarily need to start loving and accepting your body to be at peace with your internal self. But that depends on if you view your body as a real representation of who you are or an important representation of who you are. I don't believe my body represents me at all, so I don't feel much about it other than that I want it to stay basically functional and healthy, and I want it to resemble me a little more closely. Other than that... I don't think I'll ever love it.
it seems to me that it's far more important to deal with one's mental issues first and acknowledge that being trans isn't anybody's deliberate fault. It's unfortunate, that's all. Like a birth defect is, but hardly worth despising and beating yourself up over. But I think you have to reach a point where you like the person you are (not necessarily the body) inside, to be able to really love yourself more. That can sometimes take a lot of work, as it did for me. I feel like I started out in life as the most pathetic human being imaginable, and had to slowly work myself through what felt like it was wrong or right to be and to get myself up to the level of everyone else who seemed like they all had some massive head start just being normal and capable in life. I suppose that's why these days, even though I just figured out I'm trans 'properly' about 4 years ago, I don't feel that much dysphoria anymore. I know I've tried and fought hard to live this long and get through all the things I have, to the point where I'm proud of myself for managing it, without any help. It's hard to hate/blame yourself when you know you've done all you can to make things right.
