Without knowing what your PROBLEMS are; here are some generalizations:
Your CREDIT CARDS and CREDIT ACCOUNTS should be 20-30% of their LIMIT; no more and no less. This gives the best report.
Don't buy anything on credit for the near future; NOTHING!
Find out who is making bad reports on your Credit; do something about them; call them, write them, negotiate with them.
Get some money into a Savings Account. Give up movies, pizza, CD's and Games; live like you really mean it! Try cuddling instead of shopping. Do hobbies instead of traveling.
