What helped me the most is having a friend who was going through the same. Sharing your problem with someone that is actually in the same spot makes you stronger.
Exactly - talking with someone who is going or went through the same is invaluable as no one can understand you better than someone who shared the same struggle. It doesn't have to be an advice, but just the fact you are not the only one and not alone is extremely comforting.
Plus, the bond it creates lasts for a lifetime and it just takes your friendship to a whole new level. Usually the people you struggle with, you remember for life.
