Feeling like crying all day long.

Are you unhappy about something or someone?!!! Do feel left out in your family  or among your friends?!!! There could be something which is bothering you.

If you feel you cannot discuss with your known people,  do visit a psychologist.

Seems like there are some thoughts that are bothering you. There are times when despite trying to think positive our mind reminds us of certain negative things or situations which may make us feel this way.  First of all you need to vent out to a Psychologist or someone you can trust, in your case I would recommend you have sessions with a Psychologist so that things can be sorted out. Moreover a Psychologist will teach you some relaxation techniques, you can also consult online for a detailed first session so that exact decision can be taken. If you have any negative thoughts concerning yourself you must also consult a Psychiatrist. This does not mean that there is something very wrong but treatment will make you feel much better.

even though you may feel drained and less interested in activities force yourself to follow a consistent schedule that's the key to getting over this. stay motivated. exercise. talk to a close friend or family member about your feelings it really helps.
