Going vegan - advice wanted - Lemmy.World

Hi all, I am trying to go vegan since quite some time. But this is harder for me then first thought. I am looking for any advice and maybe some had the same hurdles and can give some tips and tricks. There are two major issues for me currently: - I am on the spectrum. Major changes cause me stress. - I have to control my B12 input for medical reasons. The last one is complicated bit I am certain there are good guides out there, maybe someone has one? The first one on the other side seems unsolvable to me. While I am down to one non-vegan meal in a week, replacing the last one leads into the stress cycle again. I also tried replacing my stress snacks, for example mixing them with other snacks, and “phase them out”, it did not work till now. So, either I have to find a way to replace my snacks, or get rid of the last non-vegan meal. Any advice is welcome, giving up is not an option. Loki
