Hello Friend, Good that you are seeking a help. Looks like you are carrying different emotional problems and obviously you won't be able to take steady decisions. Solution is to first figure out the root cause for your mental stress and explore the recovery plan. You may need a guidance of psychology counselor to assist you in this process. Consult me if you are OK for online session.

Tremors, feeling anxious or nervous, sense of panic, sweating, increased heartbeat, feeling of impending doom, stomach discomfort, dizziness etc are signs of anxiety. These can be debilitating. If the anxiety is overwhelming, consult a Psychiatrist at the earliest. With the right medication and counseling, it is likely your symptoms will improve.
