I have come back to raw vegan on Dec. 30th too (but I was low-fat raw vegan for 5 months last year and went back to an organic meat/raw dairies/fermented grains for 3 months until after x-mas). I had stopped the raw vegan diet because, like you, I felt like all the efforts I was putting in the diet (the low-fat raw vegan 80/10/10 was crazy hard for me) was not giving me the results I was hoping (migraine release, energy, bloating, etc.).
Then, I met a long-time raw foodist family in December and talked about it with them and they told me that 5 months is a very short period to detox 30 years of unhealthy eating, that even them, after 6 years of 100 % raw food eating were experimenting periods of detox.
So, I feel like telling you the same thing... 1 month is still very short... You are still detoxing, that's for sure. Make sure you eat enough calories, though, since that can lead to feeling tired.
I personnally feel tired and not so hungry this time around (the first time I went raw, I was ravenous and it was very hard). This time, it's much easier, but like you, I don't feel super energized yet. Give yourself some time and keep the raw diet!
