Blogger is ticking me off!

I really don't know what the heck the problem is... I've been on Blogger now for a few years, everything seems great, the all of a sudden logging in and leaving comments on other's blogs isn't doable. I'm not hacked, my account simply won't let me leave comments. My sign in doesn't stay... etc, etc.

So, dammit... for those who know how to fix this issue please let me know. I hate to have to move over to a different blogging site, but I will if I have to. ugh
