<human>: Can you succinctly summarize the text in 1-3 sentences?

Background:  I want to fix a lot of personal problems that I have with myself.  I don't take care of myself anymore, my mental illnesses add stress to the relationship (at least, I feel that they do), I'm unhappy with who I am as a person, and I don't love or respect myself nearly as much as I should.  I've been struggling with my self-esteem for a long time.  My boyfriend has been nothing but supportive through the whole thing, (he has tried to help boost my self-esteem, has listened to me when I have my bad days and gives me advice, been nothing but a loving individual to me, all in all, he's pretty great.) and when I talked to him about all of this, he says to do whatever will make me the happiest.  I feel that by working on myself and finally being able to love myself, I will be able to love another more effectively and be a happier person in the long run.

To clarify:  there isn't another person that I want to date, this is all me.

Am I doing the right thing?  I am in love with this man and doing this seems so selfish and terrible.  I'm afraid that I will lose him forever and never be able to even be friends with him.
<bot>: I don't love or respect myself as much as I should, boyfriend says to do what makes me happy, I'm scared of losing him forever and feel like a selfish asshole.
