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.
