Anyways, in Islam whenever someone is prevented from doing an action that'll get him closer to Allah, it's called "waswas" which is the whisperings of satan. For example, if one were to sin, he may feel guilty to the point that he avoids worship because of feeling unworthiness or shame for having committed his sins. Similar to when a child may avoid his parents when he's done something wrong. Instead, he should continue in his worship, repentance, and good deeds so that his sins are forgiven and he can become a better muslim.
Also if you've done wrong in your past, well it's in your past. There's no point to dwell on it. You just have to acknowledge it, make right what you've done wrong if you can, and move on to being better and not repeating your mistakes. No one is perfect, and if you remember a specific thing that you've done just ask for forgiveness for it, and do something good to replace it.
