Help Me

I have let myself fall into a hole.  I am a 45 year old woman. I am a military veteran, I have a BA and am considered by most of my peers as an intelligent, successful woman. I started a second career four years ago as a high school English teacher. I was let go from my job last year due to missing too many days of work. I failed as a teacher. I stay at home and do not tend to my daily life until the last moment. I am on unemployment and live alone. I need to find my life and get back out there. I hate being this way!!!! I just stay home and isolate myself from anyone or anything that requires getting involved or activiely particiapting in life.
