I think I've been getting steadily more depressed throughout the lockdown. I'm actually considering getting help/therapy for the first time in my life and emailed my local 'Mind' today. I'm just finding life really effortful. I've not had a great run as I moved back to London for what I thought was my dream job, but as the most junior at the company, I was working about 20 hours a week unpaid overtime, had a female boss who bullied me and after all my effort I didn't pass probation (a fairly common thing in this industry, but still a blow to my confidence.) I got another job straight away temping but then got furloughed due to the office closing. Now my furlough has ended. My time at the first job was horrid but it was the kind of role that pushed me and it massively increased my social and professional confidence. Throughout the lockdown I was pretty isolated, seem to have lost all my confidence and literally can't find joy in anything. I saw my DP for the first time in four months at the weekend and didn't even enjoy that as much as I'd imagined. But now he's left again I feel very low and tearful. I think after having company for the whole weekend to go back to a silent flat just feels hard. 
Everything I used to enjoy - films, reading, going out, all just feels a bit flat now. I don't think a single day has gone by during lockdown that I haven't had a drink - normally several. I'm job hunting again now but struggling to drum up the enthusiasm even though I desperately need a job. I was hoping that as things resumed I'd start to feel more positive but I'm really struggling. I've also gained over a stone and feel unattractive. Weirdly when my professional life was horrid I felt much happier in my personal life and really treasured my alone time. I can't seem to get the balance right!
Is this a serious issue I should pursue professionally or are a lot of people feeling like this at the moment. I've never suffered from severe depression before, but I've noticed my anxiety levels have skyrocketed in combination with the 'flat' feeling.
