Mental harrasment At govt office

Hi, I working in a PSU for past 3 and half year. I am working in Mumbai. My parents lives in Delhi and my in-laws house is in Bihar. i got married in 2019. My husband was trying to get job in Mumbai so that we can live together but he didn't get job so he continue his previous job which is in TN. From 2019, i have taken many leaves because sometimes i have to travel a lot to see my parent & my mother in-law, who are old and some time to my husband. Even if i applied EL i always done my most of the work, still i have to face so many verbal comments about how much i leave i am taking. i was diagnosed with PCOS because of this i was unable to conceive. i was in depression. In last year in Feb month, My section was changed, and my new boss started harassing. Work was new and he was just sending me mail that i am not doing work properly. During that period i went to bihar to attend my brother in law's engagement. After my leave ended, I did not returned to work and continue to stay with my in laws, as I had back pain issue I informed him during conversation that I can’t come. He didn’t take any action. I was doing my work during that time. After 14 day he told me not to work and apply leave. I applied leave from that day. Now he is framing me that i told him that I was in Mumbai and after quarantine period I was going to join office. After that I didn’t get the salary of that period and after that he wrote in file to treat that period as dies-non and he also pointed out in file that how much leave I have taken during my Job period. He is a union leader also. I know I did mistake by not taking action at right time. but I was facing worst period for me. At office I have to face so much verbal comments from the member of the union. Now my husband is outside the country from past 3-4 months. And I can’t leave the job due to heavy bond amount. I also applied for mutual transfer but past 1 year but not response received. Now other person got promoted and I am unable to take mutual transfer. My work place is like hell. I am facing too much of depression. What should I do?
