。
Nobody wants to hear my opinion.
Literal
Anyone [topic-も] my opinion [and-such-など] hear want-not.
誰も…ない ('nobody') is the negative pronoun pattern. 聞きたがらない uses ~たがる ('to want to,' visible desire) in the negative — others visibly don't want to hear. など after 意見 adds a self-deprecating dismissal ('something like my opinion'). The sentence expresses social isolation with characteristic Japanese indirectness — the speaker doesn't say 'nobody listens to me' but rather 'nobody wants to listen.'
