surrounding yourself with decent people if possible.
This.
If decent people aren't available, don't surround yourself with just any people, it will just defer the problem into an even worse outcome. I know, I have been there. The people I was with on the surface were polite enough but weren't even interested in forming the most basic emotional links. I wasn't being emotionally fed and I am still not to a sufficient to a degree, but I am better without them as I was feeding my emotional energy to them and got nothing back. That said, we are here for you if you need it.
Depression has many underlying causes. For me it was anger. I was a ragealcoholic. While I rarely directed it at others, it was directed internally. It was both causing my depression and my method of self medication. I finally got my anger in check when I was told to stop fighting anger. Anger has a place, anger is useful, I was abusing it.
That said I was and still is fundamentally bi-polar. My struggle isn't over yet despite years of different treatments. The current medication is great for keeping me emotionally stable(Not dead), But has done little to stabilise the more physical symptoms like the inability to have normal sleep patterns or getting rest from sleep, lack of energy, mental clarity or the short manic like periods where I have lots energy, but none of the judgement or clarity to use it other than the increased reflexes and tirelessness for sports.
Here is a
directory of english speaking providers you can search and some very important phone numbers. If nothing else,
this maybe of help, but they do charge a fee for their services.
While GPs mostly deal with physical aliments, they know enough to send you to more specialized care and do care about your mental well-being. Psychology is more than an art than a science even today. Do not be discouraged if you find something doesn't work. Maybe it wasn't right for you and might very well make things worse like it did for me for a while. You need to identify it is wrong for you and move on, like what you have already done by coming here. It could very well be your initial diagnosis was wrong, but you have to let the process play out until you find the solution for
you.
You have already started the process of getting better, keep going.
