I'm sorry to hear about your problem and I have a lot of sympathy for you and I worry that you say you have a few friends 'here and there' but still feel low.
I wish I could say something constructive but if I told you I was never a 'popular' person myself, that might not be what you want to here, besides I gave up alcohol 18 months ago so going to parties is out of the question for me.
I hope you are in a better mood when you read this, please don't get to down, buddy
