I am able to understand ur difficulties. Many of the symptoms which u have mentioned is seen in people with depression. Depression makes a person sensitive and irritable to things which they were able to tolerate before and lead to interpersonal problems. People try to do many things to improve their mood themselves like eating more, spending more etc. but without much effect like in ur situation. V would need to know few more details like ur sleep, energy levels, interest, stress etc to give appropriate suggestions. Depression reduces the motivation and interest in a person. 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!!
