There’s a lot of resources which aren’t just “google it” tho, check out https://veganbootcamp.org/ for example, they’ll help you through getting started.

Sustainable eating is cheaper and healthier - Oxford study

Your situation is unfortunate and if you truly can’t afford plant based options which are practical for you then you can’t afford it.
But a lot of people just refuse the cheap plant based options, rice, beans, frozen veggies, potatoes and so on aren’t expensive.

Able-ism sucks and people shouldn’t be telling you to just go forage, I think part of the reason some vegans react negatively to it being mentioned is that it’s often brought up by people who aren’t actually disabled but just use other people’s disability to excuse their own destructive and cruel habits.

Cats and dogs can thrive on a plant based diet

That’s flat out wrong. Cats are obligate carnivores, so feed them vegan diet only if you really want them to suffer horribly.

Wild animals don’t have the capability to consider the consequences of their actions

If you consider the “capability to consider the consequences of one’s actions” as the ultimate method of determining if killing is OK or not… then you should be equally fine with mentally disturbed humans killing other humans. Are you?

Do you normally base your morals on what wild animals do?

Let’s not involve “morality” into this, since morality is a very subjective thing. The morality of abortions being an excellent example. It also puts the whole discussion about, say, euthanasia in a very peculiar spot.

Also: what about the morality of extreme deforestation to make room for farms growing vegan food? What about the morality of the increase in carbon emissions, the destruction of topsoil and reduction of biodiversity that soy farming brings?

The problem with meat industry is that, well, it became an industry. Excess is the evil here, not the ACT of consuming an animal. There are plenty of ways of giving animals excellent, pleasant lives and then ending these lives in a way that produces no fear, no trauma in them. Or even awareness of the fact.

We are all just life. Life starts, requires fuel, and then ends. Sometimes life kills other life in order to get the fuel, and that’s fine. What we, as the most technologically advanced form of life on this planet can do, is do all in our power to ensure that while all the forms of fuel remain available to us, we do so without causing excess harm. Which also means things like growing meat in labs instead of obtaining it through the killing of animals, of course. I’m very much a fan of the concept of lab-grown meat, but that’s just something that’s not obtainable on a large enough scale in the nearest future.
