Body language. You sound like you have enveloped yourself in a dark cloud with rain pouring over you. Doesn't matter what you say even if you have a smile on your face at the time, people see your body language and don't want it to surround them so they stay away. Instead of reaching out right now can you reach in and find some kind of spark? If you can, it will show to others and they will be drawn to you. I say this because I have noticed this with myself. When you are down people stay away and some will even kick you when you are down....human nature? Once you have a grip on things and don't need people as much...they show friendliness. I shake my head at it but it is the way it is.
