Hi @Kizzy2
As introduction, I was employed in people management roles for over 37 years. Unfortunately, what I learnt over this time is that hard work and conscientiousness often go unrecognized. Moreover, I learnt that a small number of people will deliberately undermine their colleagues, as a means of gaining favour with supervisors.
With these considerations in mind, their might be benefit in you convening an initial meeting with your supervisor to discuss your concerns. In this regard, I recommend that you prepare some speaking notes and if required, take a support person with you.
While not knowing the specifics of your situation, your colleagues attempt to prevent you from entering a room, is highly inappropriate. As such, you need to establish a document trail and touch base with a union representative and a member of human resources. In both cases, please remember that these people are there to help, and to adopt a conciliatory approach to discussions.
Lastly, it seems that your obvious resilience and coping skills are being tested by a person who is somehow threatened by you. As such, the key pillars of mental health including, getting good sleep, regular exercise, moderating the consumption of alcohol, and 'taking the time to smell the roses', are great ways to foster wellbeing and for keeping any unhelpful emotions in check. Subject to how things work out, making an appointment with a career development counsellor, might also be beneficial.
