Everything bad

I have done a lot of work over the past couple of years and often feel strong and good. Then the feeling of bad comes over me and it seems I never made any progress.
I’m in one of those moments now. I see trouble and challenges all around me now. The few things that are going well in my life seem overshadowed by those that are not – which seem numerous, too numerous to deal with. I’m also having the urge to break connections with people, some of whom I do not want to break the connection, others with whom I do, but don’t know how to do it.
I feel angry and crabby and don’t know what to do about it. I am concerned about overreacting or under-reacting. It just feels all is spinning and I just need quiet alone – but then I am not moving forward on anything.
