If I have lots of debts, is there any other way to solve it apart from filing bankruptcy?

There are lots of ways to repay debts without filing bankruptcy. What options have you tried till now? Have you tried to settle your debts? Have you tried consolidation? How much do you owe?
Attend a credit counseling session first. Get a smart budget plan and know about a few money management strategies to pay off your debts. If you fail to repay debts even after that, then it's better to settle your debts. Bankruptcy is your last option.

I would rather suggest you to go for the debt settlement option. You would save a good amount on your debts if you hire a reputed debt management company. They will negotiate with your creditors and suggest you a suitable repayment plan.
