What to write next?

Now that I've finished my third self-indulgent memoir, I am at a loss of what to write next. Should I discuss politics or literature? Should I write an articulate rant? I considered writing another memoir; perhaps about something that has nothing to do with amusement parks. I have also considered editing all my memoirs, for I feel that they do not have enough semicolons. I do not know why I treat these memoirs with such reverence. Perhaps it is the amount of detail and work I put into these, taking days or even weeks to write even a single entry, editing and re-editing them. I certainly don't put as much effort into my other entries.
If I wrote another one, what would it even be about? One idea I had was that I would write about a trip my father and I took to The Shelburne Museum. I've also thought about writing about another amusement park trip, but I was afraid I would make myself redundant.

Normally, my mind is swimming in ideas about what to write, ideas I quickly forget due to the fact that I've got the attention span of a squirrel. But lately, I've been having some 'writer's block'. I don't know what ideas to use (if I can even conjure any to begin with) and when I do actually start to compose something, I begin to doubt its quality. Am I using too many details or not enough? Is my grammar correct; where do I put a semicolon? Did I use that semicolon in my last sentence correctly?
It seems of late, that my anxiety has gotten worse and worse. Every aspect of my life is fraught with intense feelings of anxiety and nervousness. My mind overcrowded with screaming obsessive thoughts. Then, the depression and the despair sweeps through. Nothing seems right, and everything my friends do or say annoys me.
I've had a lot of unwanted drama in my life lately, most of it of my own making. Things I should have left unsaid, now out in the open. Misunderstood words coming back to bite me in the ass. It feels like my life is falling apart, and at this point, I'm willing to let it. What else can I do? There does not seem to be much I can do to stop fate, so I am going to have to take things as they come, and learn to accept the inevitable.
