Pennsylvania is an at will state. That means that unless you have an express employment contract (or are part of a collective bargaining unit), you can be terminated at any time for a good reason, bad reason, or no reason at all. Unless the termination is in violation of public policy (which generally means an enactment of the Pennsylvania legislature or U.S. Congress) , there is no cause of action.
If you believe you have been treated differently than others because of a protected classification (i.e. your race, age, sex, disability, etc.), then you may have a claim of employment discrimination. Gender affinity is only protected in some municipalities (Philadelphia, Pittsburgh, Allentown, etc.) but not under state or federal law.
Otherwise, the circumstances you describe do not appear to outline a viable claim for 'wrongful termination' in Pennsylvania.
Personality conflicts such as what you appear to describe, are not actionable at law.
As an at will employee you may be fired for a reason, no good reason or no reason at all other than illegal discrimination. Discrimination against you based on age, gender, race, religious beliefs etc.... may give rise to a different answer. If you do not have an employment contract or union to represent you, your recourse is limited.

If you have a discrimination theory about retaliatory discharge or hostile workplace conditions you'll need a lawyer.
Check with a lawyer in your locale to discuss more of the details.
Good luck to you.
