Along with medical help, caring people around (this is not guaranteed always), you can try music. This is a "just-in-case-if-it-helps" view and not a substitution for medical help.
In case music affects you (not just a liking but a profound impact) , can try this:
Carefully select good music and listen to them, try to feel the emotions they invoke. Try to "respond" to that emotion the musician is trying to express. Explore instrumental music (or music with less vocals - not rap or death metal or any distracting lyrics) of different countries. It's okay if few types of music makes you depressed. It's called catharsis and a good thing. Point is you need to find music of your liking. Don't listen to anything that comes in radio or streaming apps. Keep the playlist handy and listen to them at any time you are allowed to listen music.
Personally, music has helped me overcome a lot of not-very-serious anxiousness, mood swings, negative emotions, suicidal thoughts and very high levels of depression.
