I feel like my social skills have recently devolved

I (30M) recently got out of a divorce from a 7 years marriage, and I feel like I lost the ability to make and mantain friends. I see myself constantly alone, specially weekends, and basically accepted that I spend most of my time by myself.

Many of my friends were “inherited” by my ex wife after the divorce, and while they aren’t hostile to me I dont feel comfortable reaching out to me. The ones that I keep contact and new colleagues from work I feel uncomfortable to constantly bug them for company and I dont want to feel like they have to babysit me, socially-wise.

I also noticed I am constantly brooding over my actions and words when I do go out with friends and coworkers, obsessing that I am actually a very unpleasant company to have.

I was always a very outgoing person and never had a problem to mantain friends. Yet here am I. My biggest issue is an almost inability to reach out to people. Sometimes it almost feel like I am asking them out on a date, it just makes me so nervous. I was never like this.
