Hello Meris.
I think it's not your fault if anything happens, because you are just going through a lot, and she'll support you if she's truly a nice girlfriend.
Nothing wrong with that... there'll be times where she'll support you, and there's going to be times where you support her. Love and relationships at its core ..
is a give and take kind of thing.
And i think this relationship is going to work out well
One reason is because she's concerned about you, and sometimes she's just taking more time to reply cause she's thinking about your sake.
She doesn't seem like the kind that will abandon you, and the way she makes you happy only reaffirms that.
But .. if you really fear running her off...
It's best to also use other means to express your feelings, such as a diary to help document and think about what you go through, but remember to write it in a positive way.. there's no reason to doubt yourself.. your past experiences are what caused your depression, and it's time for you to let them go. This is a proven theory because when you doubt yourself a lot (thinking that you 're doing everything wrong is one sign of that ) you make more mistakes. So just believe in yourself, and not overthink everything. I know that you care a lot about other people and her , and that alone shows compassion.
That compassion is going to hold things together, and fortunately i see an infinite amount of it in you.
I also think that it's good if you got into music ,books and other calming habits that will help you relax your mind. Nothing beats a good book when you wanna relax and de-stress!
If you need any more advice or just need a friend to rant to, I'll always be around. Rant to me anytime!
