I see. But i still think they are 2 separate problems, thats what i am really focusing on. Dont expect a job to solve the loneliness problem, thats putting too much on the job. What if you hate your new coworkers?
Not the wisest to try to kill 2 birds with one stone, thats all im saying.
Also, dont be driven by some random headhunting call. Look for a job when YOU want to. The way this job has been treating you, i dont see them dumping you on short notice, for example. They seem kind.
