4 months unemployed and it's driving me insane

I was laid off earlier this year for the second time from a job I didn't enjoy. I had maybe 4-5 leads where I was in the final interview stages, only to be rejected. These jobs had over 100 applicants and were reposted many times, and are still looking for that unicorn.

They weren't all perfect in terms of seniority and pay, but beggars can't be choosy. So, I attended them anyway, but to no avail.

Now the lack of income, routine, and sense of purpose is driving me insane. I felt I was more than qualified for those roles and would perform well at interviews, but because I'm a transsexual woman, I suspect the managers' biases and prejudice are the main barrier. It is what it is, and there's not much I can do about being trans, but I'll be lying if I didn't think it was the main deterrent.

Does anyone have any advice besides the have routine and such on how I can get out of this mental decay, boredom, and overall sense of feeling unfulfilled? Thanks!
