I don't know it if should report this or not

I don't know if I'm getting bullied or if I should report it. I am rendering for work because I always feel bad and negative and the work is really heavy. All this time, I blame myself for these negative feelings. Then yesterday while working from home, I accidentally heard my supervisor and other coworkers mocking me. They thought I already left the virtual meeting room. When I realized they were talking about me, I started recording, but i only recorded the part where she said she hated me and now I am resigning, then their conversation when they realized I was there.

After that, I ask my senior to help me finish a task. But he rejected. He screenshot our convo and sent it to our groupchat (idk if it is wrong sent or it is supposed to be there), then he chatted "where did you get this thing?". To let him know I'm in the group I reacted laugh emoji. Then he suddenly replied a joke.

The third one is their intel disguising as a friend. She called me and I also recorded. She's trying to ask me stuff – that if I answered, it will harm my reputation. So I asked her directly why she is asking that, did someone told her. She was shocked and said she do not know anything of what I'm saying. She kept talking and talking so on.

Lastly, one of my seniors wanted to leave and gave me her tasks. Note, I already agree to takeover over her job twice for this week, and she wanted to leave again today. Since I've had enough from their BS yesterday, I said I'm sick and go on a leave today.
