Prevod - Portugalski brazilski-Engleski - Odeio ficar assim, não gosto nenhum um pouco...

I think the first sentence would read better (and sound) in English as:

I hate being this way
or
I hate being like this

the verb after "hate" takes the present participle "being".

Thank u for ur tip, Lily! :-)

Hi Diego

Maybe "I don't feel very well" would be more accurate here.

"I'm not feeling very well " gives the impression of a momentary indisposition. Like a headache...

I think that what the requester wants to state is a more permanent feeling.
What do you think?

Yes Lily! Thinking better you're right!
