Don't let your pain and irritability separate you from family and friends. Attempt to problem solve those things you can control. Do it in short periods of time. Set goals that are flexible and reasonable. Goals should be positive, do-able, can be measured, clear and defined in terms that can be achieved, and important to you.
Fresh air is a great tonic.
Sit in a chair. Absorb the sun's rays, feel the breeze, listen to the sounds of nature. Counseling can help you deal with grief issues, depression, anger, financial stresses, etc. Be in control. Stop when you feel tired.
