I’ve been sad a lot of my teen/adult life but it’s reached new heights of depression recently I found out I have been getting cheated on and it’s so dumb coz I should of known in hindsight but anyways unrelated really, I am very depressed and I’m struggling to live life knowing how grime it really is I’m such a hopeless romantic and I used to think that was great but now I feel so hopeless ahha but like what is the point living when the person you thought meant everything never even had basic respect or love back. I know I could just move on but chances are it will almost definitely happen again we live in a time where everyone cheats it’s so sad. 
Anyway have you had this mind set and did therapy help?
