becoming more depressed

I feel like my life is going down a downward spiral. I lost my job due to redundancy and I have been unemployed for 2 months ish. I don't have motivation, it's so hard. I know I will apply to so many jobs then they will reject me. My supervisor and coworker got a job a month before we left. Then my supervisor decides to post a picture of her new work badge and her smiling on whatsapp. I don't know what that was about. I blocked both of her accounts. It doesn't help when I am depressed. She asked me if I have a job but I gave her an update then blocked her. I don't know why she would care when she has been treating me and everyone like crap. It was constant walking on eggshells and being told off all the time. She was rude to me that I couldn't do cleaning tasks so I don't believe in myself and I think I am not doing well. Everyone was shouting at each other, it was so toxic. I am so glad I am out of that environment. I don't even miss work. I miss chatting to my co-workers. My supervisor seems narcissistic. It's so hard to pick myself up. I am doing little things. I have some hope but it's so frustrating being stuck at home. I am going on walks and I have an employment adviser who I have a meeting with every week on teams meeting. I have thought about ending it. This situation brings up the other issues. No one talks to me apart from my sister and brother. I tell myself I have no reason to be here. Then I have people telling me to call helplines but I don't know why random people care about what happens to me. or me as a person. Thanks for reading my vent.
