Good Morning Julia
It is lovely to hear from you and even better to read that you genuinely feel like you are in a better place than this time last year, I was so very very happy to read that, you have been through alot and to hear you feel better, even a tiny bit is fantastic.
Self esteem is a funny old thing and i believe that it is something that changes during our lives, sometimes you feel on top of the world like you can do anything and are so worthy and othertimes like you dont deserve the dust off the floor. I can see that you have put your school issues from the past aside from your self esteem and that is so wonderful to hear, those people from the past don't get to choose how you are feeling now and even though it was very traumatic for you, they didn't know you then and they certainly don't know you know, nor do they get to say how you feel about you. You write so beautifully and are so articulate and intelligent, you should feel very proud.
I would not be too concerned just yet that you feel like you can list any interests, you have just been focusing on your mental health and getting well, that is a huge task in itself let alone trying to find things of interest. As you a feeling a little better maybe you could try one new thing, maybe like drawing or even colouring in in mindful books or even writing, you may hate it and that is fine, as you tried it, but..you might love it.
I find writing so wonderful, a massive purge and get it all out, doesn't have to be for anyone else, but what you could do is write a story, about your life, how you are coping and write the ending, the most amazing ending that you would wish for yourself...how exciting...
It is a pretty lousy day here in Melbourne so the perfect day for some colouring or writing.
massive hugs to you Julia, I am so very proud of you and so very happy to be chatting to you.
