keep climbing,
I suffered from anxiety for about 2 years at which time I saw a therapist and took medicine for around 6 months (which I was hesitant to take, but my Rabbi recommended I take).
Number one, the most important thing to do is daven. Reading the words with an Artscroll Interlinear Siddur helps instill an understanding of, and feeling for the words which you say every day. The words of davening and Tehillim can help you feel closer to Hashem, and slowly build you up.
Number two, try to involve yourself in organizations which do chessed for others, or even look for ways to do chessed on your own for others. There are many people out there (older people, disabled people, etc) who need help. When you help others and exert yourself for them, it can develop your self worth.
Number three, when you aren’t davening or helping others and you need time to relax, use your time wisely by reading educational matters (such as history, sciences). This will make you wiser to understand more about how the world works.
Another thing you can try to do is travel to another city or Israel, to grow there. A change of scenery also can help get out of a stagnant situation.
Good Luck.
