Help me with some tips

I’m always alone at home, i work but when i got home is just me and mu dog. On the weekends i got nothing to do, i just exercise and go to the park with my dog and sometimes i visit my sister who lives 20 minutes away from me. I’m married but my husband works a lot. I have coworkers but not friends to go out with. I feel so lonely and i want to change that but I don’t know where to start…
