Remember: You do not have problems. You may be the problem.

I see people doing this all the time, without realising how much they are sabotaging themselves.
I know you have a lot of problems. Everyone has a lot of problems. Take absolutely Anyone as an example, they'll have problems almost as much as you. Which is why they probably do not want to hear about yours.

It is sad and you do feel like shit but do not let others know that. Please. Do not.

Most people might think you are a great person and lots of fun or that you are funny and generous or kind hearted, but the moment they hear about how depressed you were when your parents had a divorce and you were separated from your siblings, their perception of you will change completely. You might think that by knowing this they might consider you to be deeper or more rounded, unfortunately you can not be farther than the truth. Voicing your hardships makes you sound whiny, weak, spineless and other negatives which you can do without. With so much happening in your lives anyway- having other people think stuff about you is more than useless.

It sounds ridiculous. People can't be that shallow, can they? Don't they understand? ... No. They don't.

On the other side, they could also use your 'weaknesses' or issues against you.
I have a friend who was ostracised from her 'group' of friends because she admitted to one insecurity to one girl on the group who she thought was a friend. She suffered for a long time without anyone to talk to. It was so traumatic not just for her but also for her family and other friends. And the crux was just one silly little confession (which neither she nor I even remember now)

Don't let anyone use your faults against you, whether as a weapon, or in a way that maligns your reputation in their eyes. Everyone wants to believe the world is simpler than they think it is. By thrusting your innermost (or not really) problems and issues on to them, you make yourself look different from what they think.

You make them uncomfortable. They stop liking you.

You don't have problems. You become the problem.

Everyone hates complainers and whiners. Believe me. You do too. So stop putting yourself on the line and do Not tell people everything, do it only when you can really trust with your life. Remember my friend who lost almost her entire life for one small fact, she thought she was talking to a Friend. Save yourself. Don't bother. Let people think you are always happy, always laughing, they'll like you better. :)
