I have mild depression which really messes me up in every way possible !

I have only told my gf and parents that I have the condition, but don't want to tell anyone else as I feel ill be told to man up and just get called lazy :(

I have pushed everyone away in my life and I can't stop it :(

My main reason for this question is because I don't know if I'm being stupid or it's what most people would think.

My so call friends recently have just booked a holiday away and I was never asked, but once asking them they made up some crap excuse. There reply was we asked 4 people and didn't want to 5 people. Am I being panaroid or not ?? They didn't want me to go is my feeling. Was does everyone else think :/ ?

If they didn't want me to go I would of had enough of them and wouldn't want to talk to then every again !! This has been winding me up for a few date and didn't know where else to turn too.

I hope you nice people can help me in anyway please :)
