I am not sure if I have depression and not sure what to do to improve my mind.

I met up with an old work colleague a couple of weeks ago who was visiting the area for a couple of hours and it was great.   However,  the next day it hit me that I am incredibly lonely and it has really got me down to the point that I occasionaly feel like crying.   My only human contact is zoom calls with people at work and people i see at the supermarket.
 The fact that I am flat broke and my location is also not helping

Normally if I feel low my mood is more positive after a few hours or a day at most.   However,  it has been two weeks now and I just can't shake it.   I don't get pleasure doing the things I like doing and my motivation is zero.  I have also lost my appetite.   I also now have this odd feeling like I am totally disconnected.  Like I am present in body but not in mind.  .

Any way my question is....  do people think I have depression or maybe a spell I am going through.

I hope to join a running club in a month's time in the hope to meet some new friendly people.
