Next word is "can’t". The contraction of "can not". Synonyms for "can’t" could be cannot. That makes sense. Maybe "can not" is another option but it's the same as "cannot". Probably acceptable.
And "that". Synonyms for "that" are this. Wait, "this" and "those" are different. However, "that" is a demonstrative pronoun or adjective. "Those" is plural. Maybe "this" can be used as a substitute depending on context. But in the sentence, "that" refers to a singular noun. Maybe better to use that but note that "this" and "those" are different. Alternatively, maybe that. Hmm. "It" could be a pronoun. So perhaps it if allowed. But the user didn't specify context. Maybe stick with this even though there's a plurality issue. Alternatively, maybe use that as pronouns. "This" can refer to something mentioned earlier, but in the sentence, "that" is the demonstrative. The user might accept "it" as a replacement. Let me check thesaurus.com. Thesaurus lists alternatives like "this", "it", "those". So maybe better to use it since "this" and "it" are pronouns and "those" is plural. So I'll go with this for the word "that".
"can’t" → am not able to
"I myself can’t am not able to help support with concerning that those."
Starting with "I". The synonyms for "I" could be I. Wait, but "I" is the first person pronoun. The user probably expects different words, maybe "me" and "myself", but "I" is the only pronoun that's first person. Hmm, maybe include "me" and "myself" but I need to check if those are acceptable. Let's go with myself perhaps. Wait, "self" is a noun here, but maybe it's acceptable as a pronoun in some contexts. Alternatively, maybe "person" isn't right. Let me confirm. "I" can be replaced with "me" in some contexts, but not always. Maybe "I" is the only correct form, but the user might want different pronouns. Let's stick with myself for now.

"that" → this
"help": assist
So the original word is included in the synonyms? Or not? The instruction says "rewrite all words with 3 synonyms", so maybe the original word is not a synonym. Therefore, for each word in the original sentence, provide three different synonyms, not including the original word. Wait, but the example the user gave at the end is "I can’t help with that." So maybe they want each word replaced with three synonyms. But some words may not have three distinct synonyms. For example, "can’t" is a contraction; its synonyms include "can not" but that's the same as written, but maybe other phrases like "am unable to".
