Thanks for writing your query to us.
The symptoms which you had mentioned suggest that you are in depression
Depression is a mental state characterized by a pessimistic sense of inadequacy and a despondent lack of activity. It is an emotional disorder, and nothing to be ashamed of. But often, people who are in depression are suffering from pessimistic thoughts about themselves. These pessimistic thoughts lead to even further depression making a cycle that gets hard to stop. In depression a person loses his energy to cope with a challenge.
I would suggest that you should meet a psychologist
who will be able to help you. They will listen to your problem & start counseling sessions. You are really stressed out & you need to take this initiative
