Dream job.... Industry in trouble?!?

I've been searching for work since May this year and I just feel overwhelmed with where I should be applying vs where I actually am applying. I've worked my best on my resume but I've got no one to double check it to ensure I did it right. I followed several different "how to write your resume" books and websites that I could but... Then most wanted money. I've tried the keywords and trying to tailor what I can actually do to fit the jobs I'm applying for... are resumes okay to be 3 pages long? Are bullets better than paragraphs? It's all so confusing and I've broken down to my husband over this so often. I don't know where to turn or who I could ask for help. My husband doesn't know about how to do a resume, I asked. Every denial just makes me feel like I did something wrong with my applications.

I have updated my resume-but I already uploaded it for the resume drop. How can I change it for that event? Thank you!

There are plenty of places for you to go and work at." I said "oh ok sure. See you at 4pm." Honestly, I felt like leaving for the rest of the day and not coming back. I was simply waiting for 4pm to come since I was asked by our Director to cover the phones for her for 30 minutes while she has a meeting with her. I literally cover the phones for her lunchtime EVERYDAY and she seriously has an issue with me sitting behind her at the front desk that she shares with Security. I explained to her how I was planning on staying at the desk from 2pm until 4pm until it was time for me to cover the phones so that I won't have to keep going back and forth from one department to the next. She did not say anything at that time. I really don't like working with people like that who make an issue out of nothing. This is a temporary job that I was hoping to replace and find something better with by now. How would you respond to this?

I built a career in social impact projects but I am feeling so lost right now! I get no replies from jobs and I really don't know if I want to change my life completely and do something else entirely or just going through a very weird and depressed phase. Has anyone felt like that? Like your purpose doesn't have a purpose anymore? Has anyone changed their career while still in need of work for a living?

I have a masters in Industrial Psychology and a second postgraduate degree in Project Management with Corporate Communication. I am looking to start my career in Human Resources and Organizational Development. I have been tailoring my resume based on the job requirements, writing a cover letter accordingly and highlighting skills and experiences relevant to the position. The response rate is nil, and the rejection rate is stagnant. I am unsure what more I can do at least get an interview. What can I add to my approach to get a positive response? I appreciate any guidance I can get. Thank you.

I haven't heard anything and noticed the job is still posted. Should I apply a second time?
