Kudos for coming back! I also recently changed my screen name b/c of account trouble, but hischadshus is usually a good thing.
I often suffer from lonliness, and over the years, I have tried to identify what causes me to feel lonely. For me, low self-esteem, poor self-confidence, anxiety, etc. are all factors. I am currently trying to rectify my shortcomings one by one.
Hopefully, you'll find yourself improving by doing the same.
Hatzlacha Rabbah!
