Hello!
congratulations! it's a very good decision

. I would advice:
1. concentrate on benefits not on what you are giving up
2. if it's hard for you then try at first just to eliminate meat and bread. Remember - meat is just rottening in our bodies and bread just stays in our body as garbage.
3. THE MOST IMPORTANT try not to mix food. I'm a mono raw foodist. I can tell you it's much easier just to eat two pounds of apple then trying to create something that would be similar to cooked food. There is a theory that each food has its own type of enzymes and it's better for digestion not to mix them. Why it's important? Because for me it turned out to be much easier

, believe me, there is no need to learn now to blend, dehydrate, mix and so on. Although if you want. go ahead

.
4. Well, probably THIS IS THE MOST IMPORTANT - depending on how toxicated your body is. you may feel WORSE at first, but remember that means your body is cleaning itself and after each such crisis you are closer to HEALTH. Don't do anything, just go through these phases!
Also take care of your teeth, raw foodists first year have problems with teeth, probably due to eating more acid and sugary food they didn't get used to (like fruit)
how to start? just start eating raw

whatever you want, when you want and how much you want. It's easy! After a couple of weeks you will see that it's enough for you to eat several apples or bananas and you are full! that's actually more true for mono raw food diet.
I hope I helped you!
