Feeling Lonely & Lost

Hello everyone 23M, Recently for the past 2/3 weeks I feel like I have been catching my self into a depression, all I can think about is the past years were I never felt lonely, always had someone to talk too but now ever since I’ve cut off drinking for over a year now i have drifted away from my friends and feel like I’m on my own. So I’m just feeling lost at the moment on where to start to look for new friends as at this age I feel embarrassed that I don’t have any friends to talk to anymore. Thanks in advance.
