Depression, stress

I struggle to relax at all and i barely know how to have fun anymore. The worst is when im stressed out and then im obligated to go to a fun thing (for example today took my kids to their cousins birthday party) and it really just feels like another chore. I know its sounds silly and not a big deal but its been this way for literally years causing me to feel really depressed, lonely, snd dull/lifeless. I dont think this is what god wants for any of us. Plz pray
