You should be fine but if someone hacks one of your accounts they can hack them all. But you should be fine as long as you aren't giving your information away constantly.

yes there is a problem!
1. using the same email for every thing causes a lot of trash that you don't need in your inbox it is easy to lose a very important email or you can simply delete it by accident.
2. using a same password for every thing is dangerous because if that password licks then everything your are your personal details can be tempered with plus in this day and age where we have cyber hacker and cyber stalkers including thieves can easily still your identity.. and you can go in jail for a long time for a crime you never committed
