a large number of people (amount should only be used with inanimate things)
mixed usage of we and you !
various reasons (many is redundant)
mix of singular/plural : people resort(s) to / the feeling they give become(s)
we should all make an effort to (re)solve
minimum possible ("as" should not be there)
double negative: you are no longer unable..
In fact it is advisable to use the impersonal "one" throughout, instead of "you", or to keep the whole paragraph about Felicia.
turn your life abject - this is completely wrong
First should not appear in the same clause as "usually". It's one or the other.
you say "results in an addiction", when you've just described symptoms of addiction in the previous sentence. This is poorly structured.
I have tried to rewrite the paragraph, as closely as I could to your original, though I am still not totally satisfied with the juxtapositions of "she", "one" and "we", but at least they are not as mixed up as they were, and I have eliminated the "you" elements. I have rephrased the more awkwardly worded segments.
I find there is a connection between Felicia’s habitual use of drugs and addiction issues in the broader world. Illegal drug addiction is one of the biggest concerns for a large number of people. It is a problem familiar to us all, whether we heard it on the news, or from friends, or from personal experience. There are various reasons why people are addicted to drugs. People often resort to drugs because of peer pressure, stress or out of curiosity. One may find that many friends, in fact, abet drug usage. However, after one becomes dependent on drugs, one can not continue to function normally without them. It is simply no longer possible to perform such tasks as one could, prior to the onset of addiction. As sporadic drug use continues, it results in a condition which can make one's life an abject misery. For example, in Felicia's case, she trembles and gets exhausted frequently and only the drug she is on, can solve the problem. This pattern repeats itself and she uses more drugs each time, because the feeling they impart becomes ineffectual. Such problems happen all around us, and usually we do not notice them, and think they happen only on television or in movies; unfortunately, we are wrong. It is an issue that we should all make an effort to resolve; or at least, try to reduce to the absolute minimum, the number of people who suffer from daily illegal substance abuse.
