Iām going to assume Iām addressing young people, and then my advice would be thus; Even if youāre tired of school, try to buckle down and take it seriously. You may not always learn something that you have use for, but the grades you get are hard currency in the big bad world, and if you donāt get them early, youāll be wasting a lot of time later on.
And pick a career path early in life and work hard towards it, it doesnāt matter if you change your mind later, what matters is getting a foot inside the door somewhere, anywhere, so you can acquire some form of work experience. Donāt expect things to just fall into place by themselves, if you donāt know your path in life, youāre not magically going to wake up one day and just know it. Having a job while youāre considering your options however will alleviate a lot of pressure from you.
Donāt trust society, religion, history or the media, be critical and make up your own mind, donāt swallow them prechewed from others.
And one more thing, always strive to overcome yourself and your own doubts, better you make a fool of yourself for one hour, a day or a week, than to regret a lifetime of lost opportunities.
As for your problems, I can offer nothing but the obvious, therapy and possibly medication. Sometimes depression stems from synapses not firing right, that canāt be helped by anything other than medication.
