(((NeedHelp)))), I am sorry you experienced that. The work environment you describe is definitely an unhealthy work environment. You actually made the right choice when you left. When people begin to get personal like that in a work environment that is a red flag that you are not in a healthy respectful environment and the best way to handle it is to leave. Depending on the size of the work environment if there is an HR department you can go and complain because these situations should be addressed.

No one should be picking on you for what your relationship status is or if you are willing to drink and party with others. None of that is important, what IS important is that you do your job.

Please know you did the right thing by choosing to leave that work environment. This is also true for any toxic situation you find yourself in, be it in a group of friends or in any kind of relationship.
