How can we make this LDR going?

He (27m) and I (21f) are 3500 kms apart.
We are in love, we are IN LOVE, but it's too hard...
We met 9 months ago, and we're together 8 months now (we met irl in January and February, then the pandemic started...)
We can't be living together for the next 3 years, I have to learn his language to study in his country, for my master's... he does not has a perspective in my country... he tries his best to earn money for our stable future life... i'm 21 - had a troubled past with mental health and was not able to study/work for 3 years, now, I'm rethinking my path, applying for jobs... busy schedules prevent us from seeing each other + the pandemic... my parents are not okay with me traveling alone in his country yet (i'm from a traditional country), he has to visit me everytime - he met my family, but they still seem "formal"... Even though, we're close souls and deeply in love, working on everything. But it makes me feel very bad lately - my psychological health has been worsened... again. He's more emotionally stable and supports me as he can, but i'm still crying at every night, it's too hard, even if he's right... what should we do to make it work?
