Feel Happy For Being Sad

This may sound weird...But it does happen...Feeling happy because you are sad...it is like...you feel sad because you know that you have done something wrong ...But also...you feel happy because you feel sad about your wrong doings( reread this if you cant catch the words)...This feeling can take over your entire thinking towards life..And also it can change the paradigm of your vision towards many situations...if this feeling is like remorse mixed with being proud...what kind of retarded feeling is this....This is driving me crazy...
