Today and Tomorrow is my new motto,My circumstances are similar,My 9 year old Son lives with me and I too have next to no support. In this year 2017 I have been out on my own @ 4 times and 2 evening functions wit my Son. It is good that you did a cbt and perhaps an idea to do more courses if possible. Last September I started a Teaching Assistant course at college and in the New Year I will be starting a placement in a school. It is not as nice as going out for a social evening but it is better than nothing. Like you I do not really bother with people that do not have an understanding of being a single parent, exhausted physically and mentally trying to keep everything together. Let us hope for a Happy New Year and concentrate on today and tomorrow.
