Right, it's amazing what you've achieved so far and even better that you obviously want to get back on the horse - so to speak. Woo hoo!!
10k is completely doable. Like the old 'how do you eat an elephant - one bite at a time' challenge.
Just set yourself small, achievable goals. Maybe don't worry about distance, do time instead.
So Today, aim for 3 x cycles of 5 minutes running, 2 minutes walking ( or whatever you think is achievable).
Just get out and give anything a shot, however small.
Then tomorrow, try to do a tiny little bit more.
Little and often.
Sort out an amazing playlist - Spoitify is brilliant if you can do a free trial for a month. Then you can download to your phone in case signal is bad or you want to save data.
And as for people running faster / easier than you, of course they will be, you might encounter professional runners or people training for marathons - I find it easier to visualise them in that category rather than think they are 'someone like me' as then I cannnot possibly compare myself as they are not a normal person

Running is so good for mental health and general health you are doing a really good thing do t give up!!
