Why would I feel tired all the time, low energy, no motivation, don't want to get out of bed, loss of interest in everything, just don't care-odd 4 me?

Hypothyroidism or ? You need a medical workup. Don't assume your situation just requires psychotherapy, even if this all started around same time a bad event happened in your life. I have seen patients who got delayed diagnosis of brain tumor, hypothyroidism, etc. These can be treatable if detected early. I am especially concerned for you because you did not mention sadness in your description. Don't put this off!
Depression. The symptoms you described suggest depression. Please see your doctor as effective treatment through psychotherapy and medication is available.
