Still single af in Single life

Right I’m still so single it’s a joke… I even feel like my friends are on different pages to me, they don’t want to do anything I want to do they don’t want to go on holiday as they are going with there partners or don’t have money…I’m at a loss here, ok I don’t have a partner so I decided to still do the things I want to do in life like travel and have expirences but I have no one to go with and I feel trapped like a flying bird inside a tiny cage… I’m stuck where I am and can’t fucking move. All my friends have partners and are making there own memories and doing what they want I can’t blame them for that! I can’t find anyone not even friends that want to do things. I’m really frustrated and can feel myself slipping back into depression! ( I had depression when my son was born) I have fought so dam hard to keep the depression away three years I’ve been fine keeping it at bay and now BAM cartoon rain cloud following me around. I don’t know what to do anymore I’m actually at a loss… fuck.
