Hello. Stressor are part of life. But if a person is continuously stressed it may lead to depression. As u mention total duration of 2 years is quite long. U must consult a psychiatrist at earliest.

I am able to understand how u must b feeling. Many of the symptoms which u have mentioned is seen in people with depression and anxiety. Not knowing how to cope with stress can lead to such difficulties. Depression makes a person sensitive and irritable to things which they were able to tolerate before and lead to interpersonal problems. V would need to know few more details like ur sleep, hunger, energy levels, interest etc to give appropriate suggestions. Depression reduces the concentration, motivation and interest in a person. Anxiety can cause bodily symptoms like palpitations tremors sweating etc. Dont feel bad, it's not ur fault. It usually occurs because of chemical or hormonal changes in the brain. Ur problems can easily be treated with counselling and if needed medications. Don't let ur problems affect ur personal or family life. U can also consult me online directly through the practo chat option. Best wishes for speedy recovery!!
