Proverbs 24:16 "Though a righteous man falls seven times, he will get up, but the wicked will stumble into ruin." Romans 5:2 "We have also obtained access through Him by faith into this grace in which we stand, and we rejoice in the hope of the glory of God." Romans 5:20-21 "The Law came along to multiply the trespass, but where sin multiplied, grace multiplied even more, so that, just as sin reigned in death, so also grace will reign through righteousness, resulting in eternal life through Jesus Christ our Lord." If you keep falling, get back up. Your salvation isn't dependent on your pertect performance. It's dependent on Christ and His finished work. Repent. Keep fighting. Keep pursuing Christ.
