You can only be strong for yourself. Can't expect people to be that arm for you to hold on to because that arm is going to get tired after awhile. When that person lets go of you, you fall. You fall, HARD. It hurts even more. The cuts are deeper, the scars hold on to you.
But don't stay on the ground too long or wait for someone to pick you up again. You wipe those tears and you pick yourself up.
