What should I do? (Read description)?

There's a lot of things that can help and a big advantage to having a professional who knows how to use them. 

There was a poll of therapists that showed a lot of them don't talk about the basic lifestyle things that help with depression, which is unfortunate. There's a variety of low-cost low-risk things, and you can combine them with the standard treatments and each other.

Don't be afraid of exercise. Light exercise, as little as 20 min brisk walking a day, can help, and you can add to that gradually so long as you don't make yourself sick of exercise with too much.

Things that take your mind off your problems for a while, like a funny movie, are helpful, as long as you don't let them dominate you.

Lifestyle therapy has things that are mostly very easy.

Of all the traditional Asian methods (meditation, tai chi, etc.) the one with the best evidence for helping people with mood problems is controlled breathing. I have information about therapeutic breathing recommended by psychiatrists Brown and Gerbarg and PTSD therapist Emma Seppala in my answers. This is safe and requires no training.

If you're depressed, I can't tell you exactly what you need. There's no one size fits all solution. I can tell you though that there are things that can enhance the effects of the standard treatments with office visits. This answer has details, under DEPRESSION TREATMENTS -

There are some things that you can do that should in the long term help.

For starters, I highly recommend some form of exercise it can be walking, jogging after 30 minutes it boosts your mood. With being outside as well pay attention to your surroundings and it should mean you not on your phone as much which will have some benefits.

Even taking a friend with you, someone to talk to while walking about things can be very calming.

You may also end up finding out new hobbies that you like which may help with how your feeling.

Stop begging for attention from well adjusted people and get professional help if you are really serious.   Not one person has been helped by constantly posting these nonsense questions here over and over.
