Expressing the uncertainty about having a specific feeling

Question

These is a sentence in English that is formed in the following way:

I kinda feel ((adj)) about ((sth)).

In my notation of it, ((sth)) is something (some sort of situation), and ((adj)) is an adjective expressing a specific feeling (for example, nervous, jealous, curious).

According to the general meaning of that phrase as I understand it, the speaker felt indifferent to ((sth)) prior to ((sth)) happening, but when ((sth)) actually happened, the speaker is not sure if that indifference has changed to feeling ((adj)) or not. Generally, it's equal to 'I am not sure if I'm still indifferent to what has happened or feeling somehow else about it'.

Now, my question is: how to express just the same thing in Russian, but keeping it English-level short and in the voice of the speaker? While Russian is my native language, I am going through this confusion of word choice for quite a while.

Thanks for any suggestions!

Edit: since my question turned out to be too vague and general for others to understand, I'm extending it with an example of a dialogue where such wording is used. Let's say, Alice and Bob are having a talk about Mallory. In my case, it will go like below.

A: Will you feel jealous of Mallory if he'll win a fortune?

B: To be honest, I don't really care much. After all, it's not me who'll be so lucky.

A: Okay, Bob, actually, Mallory won one million dollars in a lottery today!

B: Uh... Now I kinda feel jealous...

Answer 1

I didn't expect I would feel this

If you are looking for a way to convey a surge of emotion you wouldn't expect to feel before, I would go with что-то:

— Это, Боб, такое дело, Мэллори сегодня и правда выиграл в лотерею миллион долларов!

— Ну вот. Теперь мне что-то завидно.

Что-то particularly conveys that you didn't not expect you would feel envious but now you realize you do.

As for keeping the active voice, this depends on the emotion.

Russian tends to convey emotions and feelings using verbs like я завидую, я ревную, я боюсь and impersonal predicatives мне завидно, мне страшно, мне больно rather than personal constructs with adjectives that English tends to use "I am (or feel) afraid, jealous, hurt" etc.

If you for some reason absolutely need a personal construct here (and for this particular emotion), you could use something like:

• — Ну вот. Теперь я что-то завидую.

or a generic construct with чувствую for the emotions which don't have explicit verbs:

• — Ну вот. Теперь я что-то чувствую себя неловко.

However, the verb form does not work well for all emotions.

In addition, the impersonal form (something happening to you, not something you are doing) emphasizes that you are experiencing an emotion you didn't expect to.

I'm not sure if I'm feeling this or not

If you are to convey that you're not sure whether you are feeling it or not, I would go with вроде и, which is quite similar to English kinda:

— Если Мэллори выиграет кучу денег, тебе будет завидно?

— Честно, мне всё равно. Не мне же, в конце концов, такое счастье.

— Это, Боб, такое дело, Мэллори сегодня и правда выиграл в лотерею миллион долларов!

— Ну вот. Теперь вроде и завидно.
