You are on a good path in finding a hobby or passion to follow. It really helps to give a sense of accomplishment and feel better about yourself. After a while - you will be doing ukulele concerts for your family!!!
Me - Ive been a drummer since 5th grade. If I might say so myself - I was pretty good. Now it has changed a lot. I can still do several things - so that is what I focus on focusing on what I used to do and cant now isn’t a good way to live - believe me - I know.
Also -as you mentioned - keeping friendships alive is highly important. That can help to keep your social interaction from turning into no interaction.
This will also help with communication.

This is a multifaceted thing we live with. There is not a simple answer. Everyday - look for a new avenue - a new outlet for some happiness and joy.

For me - my faith is one of the main things that helps me every day.

Peace
