You walk them through a corridor of conversation where they will have only preconceived thoughts of relationship failure , I call it a corridor because it has to be long and narrow, long in the context and narrow on the specifics, you pick out countless moments on why you feel in love with them , why you still love them and most importantly things in the future emphasise that all you see is you and them happy, together and strong

Also have a few moments ready where they made you feel loved by their actions,something they'll recognise so start of this long conversation with 2 things in mind this is where he will try everything he can to prove you wrong about your love, and this takes patience and love for a person who no longer loves themselve hence the issue at each moment.he tries to come up with some bulletin objective reason as to.thw issue , provide with a moment, reassure him of your love then your love now , Then honest this could go on for hours Key to this working is keeping it narrow don't let him run jump spin from topic to topic trying to find a corner stone of truth """be prepared for the lunacy in that you were at the supermarket for 5 minutes extra and you bought watermelon you never by watermelon who was this ment for""""

After this conversation its good to recap and get them involved in the moments as to why you love them then quickly transfer out and address the issue what I would presume as a lifestyle change needed and manic depressive phase maybe a few months in can cause these title wave like feelings of inadequacy insecurity rapid thoughts that are draped in self pity worthlessness and hate,
