<human>: 19 F (Me), 21 M (Him). We've been an "official" couple for about three months, but have been together for longer (around seven months).

First of all, I'm kind of fucked up. I had a lot of bad experiences from my past relationships, which is why I think I'm insecure and have a lot of trouble trusting people now. I get depressed really easily, and when things get way too distressing, I hear "voices" in my head, or cut myself.

My boyfriend has been incredibly supportive and caring. He's always trying to help me, always trying to protect me. And I believe it has worked. But there are still things that bother me.

Most of the time he's around, I feel great. But sometimes, when he's not around, I feel lonely. And with loneliness, comes everything else. I start getting depressed, and can't snap out of it. Although I've made progress on these issues since we got together, I feel I'm too dependent of him. I'm scared this will be too much for him, but I don't know how to stop. I know I'm supposed to look for things to do when he's not around, but when I start feeling lonely I just can't, I don't feel like doing a thing.

I just want to get better, be a better girlfriend, and make him happy. But I don't know where to start.

PD: Sorry about mistakes, english is not my mother languaje and I'm very emotional right now.

Could you distill the essence of the text into 1-3 sentences?
<bot>: I have a lot of issues. I'm okay when my bf is around, but sometimes when he's not, I get really deppressed. Advice?
