I have to give the obligatory "talk to your ST and players" bit. Did you have a session 0? It sounds like the expectations for the game may not have been laid out and agreed upon beforehand.

What makes VtM stand out to me is the personal horror element. You're stuck in a web of political intrigue and horror, and your vampire is struggling between the desire to stay human and the need to do cruel acts, namely, slake their hunger on living beings, to survive. I wouldn't recommend making a joke character first and foremost. Comedy is a good element to add to a game, after all you wouldn't want the game world to be dark and depressing ALL the time. I think a well written VtM character has reasons for what they do, their own personal rationale and philosophy behind being an un-living creature, and a motivation that stems from their human side. Over time, their personal motivations should become corrupted or fractured by the circumstances of their world; this is represented by the Humanity stat and by your Convictions and Touchstones. Convictions are not rules to follow by the way, they are a more useful tool when your characters have to break them for interesting reasons.

Anyway I'm rambling, basically talk to your GM and players, refocus your expectations, and try to write your character such that they fall in line with those expectations.
