You might not be in a place of maintaining contacts with people. And none of these people sound like much of a commitment material, so I am not sure if it’s a commitment issue.

I think the biggest commitment would be commitment to stay sober and get help rather than commiting to communicating to random people.

Since you are homeless, jobless, in active alcohol and drug consumption and without proper treatment, I’d not worry about all these people. Focusing on your own health might be the best way to spend your time and energy .
