what do i do when i feel like the world is against me and when i feel lost in life. because i miss someone

Well if you miss someone then tell them you miss them, even if its an ex boyfriend or an ex bestfriend. But the one thing you dont want to do is go through the pictures you have with someone or the person you miss because that will hurt like s***. And hun the world is not against you, I felt this was once before and i looked through pictures and it really hurt so dont do that and I know youre strong enough to get through this even if i dont know you I know you can get through this. Just take your time with things and surround yourself with people you love and that makes you feel happy and do the things that make you happy with the people that make you happy. If you need to talk I'm here it will be okay, trust me.

the aorta is the large artery leaving the heart branches into smaller arteries, which eventually branch into capillaries.the arteries carry oxygen and nutrients away from your heart, to your body's tissues. the capillaries are small, thin blood vessels that connect the arteries and the veins. the statement that arteries carry oxygen-rich blood to capillaries is true. veins on the other hand are blood vessels that take oxygen-poor blood back to the heart.
