I'm so sorry for your sad experience, but what you'll learn is some friendships are very fickle while others (few)seem to just root naturally. Some are lasting others for a time. Never tell all to any friend as it could come back to bite you.
Some I thought were my friends because they were always visiting me, turned their backs on me when I was confined to bed, but others who I barely knew came with dinners, to visit, offering to babysit, etc. The only way to know a true friend is to be down and out and see how they treat you.
My husband, retired, spent a great deal of time helping a young couple next door with all sorts of fix-ups, installations, snow blowing, etc. The wife thought him a big fool for doing this. You can only be responsible for what you are, say and do. If another doesn't value a friendship, it's not necessarily your fault, it may just be the type they are. Some people are just 'takers' in life, and if you give that's fine, but if you need, they become scarce. Generally, those that ask for the least will offer the most and visa-versa.
Hope this helps. Never give up, because you deserve to grow and find good friends. They are out there.
