I am able to understand how u must b feeling. Concentration difficulties can commonly occur 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. We also need to check if u have
thyroid or
vitamin deficiencies. 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!!
