I'm sorry your weekend wasn't so good. I understand those feelings of jealousy. I have felt an outsider all my life, that people don't include me in on much, if anything, and when I am being social I feel like I am not there or no one cares. I get so jealous when my friends see other people. I know it's silly but I get so jealous. My sister gets invites to go out with MY friends and they don't invite me, and it hurts so bad. I feel so awful about myself, and then I start to get angry, hate everyone and push them away. In the moment of anger I do things like delete them from my phone or on facebook and when I've calmed down I think, oh my what a stupid thing to do! I feel abandonment all the time, and i understand your situation would have triggered you. It is so hard to find friends or meet people who you can share a meaningful relationship with. I applaud you for reaching out though and having such great activities in your life. I feel so rejected right now I'm barely leaving the house.
Hope you are feeling better. Big hugs to you.
