It goes through loneliness, rejection and rummaging.
The most powerful thing what I learned was about the rummaging. If you focus your thoughts on something else even for two minutes after your brain gets hold of something stupid that didn't work your way 7 years ago, you start feeling better fast! (Rummaging is also bad for yer health).
Start getting powerful there, folks! Mental health matters as much as physical!
If you're ever having these feelings of loneliness or ineptitude. Reach out and talk to someone. It doesn't have to be about anything at all, but try to keep connections open to loved ones. If you don't have anyone to talk to, write it down, but it's very difficult to fix this on your own. Mental health is difficult and it's almost impossible to get a new psychiatrist/psychologist right now in America.

Different difficulties in life and levels of strain on the mental strength require different acts to get the balance (back), to different people.
Having a bad day is a whole different caliber to childhood traumas, for example.
Talking to (non-professional) people, writing, drawing, generally doing creative stuff, chopping wood, letting some aggression off in video games can help and are small, easier things you can do to try help yourself.
Some groups offer trained volunteers to talk with you about stuff and free phone calls in times of crisis.
Professional help and medication is next level.
I'd say that therapy is more important than medicine. While medicine can help more easily with a much smaller fuss (and bill), it's still a temporary help and the effect wears off when you stop or run out of medicine.
If you get rid of your problems through therapy, you might get rid of them for good and even strengthen your character and also grow chances of being less vulnerable to them in the future!
