Late night feel the loneliest

After pregnancy I cut off a lot of friends due to depression.. also my friends didn’t had kids so they dunno what I was going thru and didn’t bother to check on me too... now my baby turned 1 recently. I noticed I hung out with families more than friends. I lost my friends except for one whom really dote on my son and became his godma . I feel lonely... it’s been very long since I went out with a friend
