A second opinion will need to come in the form of visiting a mental health professional in-person. I can only offer general information.
You mentioned that you are “unable to properly explain anything” but your letter is clear and articulate. It doesn’t suggest a lack of clarity in your thinking. It is indicative of an intelligent person who is in emotional distress and who doesn’t know why. It’s common for people to not know what is wrong. They know that they are suffering, but they can’t identify the source. A mental health professional could help to both determine the source of the problem and to develop a plan for solving it.
It’s possible that you simply haven’t found the right treatment provider. Mental health professionals are not all the same. Some are better than others. You should interview at least 5 to 10 mental health professionals to find the one with whom you feel a connection. You might also try medication. It might help to decrease some of the more bothersome symptoms that you face on a daily basis.
If nothing else seems to be working, you might consider ECT, as suggested to you by the hospital staff. You can read more about it online. Though it is often considered a controversial form of treatment, many people have found it helpful. For some, it has made a dramatic improvement. It’s typically considered a treatment of last resort. I’m not advising that you do or not do ECT; I am advising that you thoroughly investigate all possible options. Please take care.
