Mistakes finding

Hi teachers, could you help me correct this problem/solution essay on reverse culture shock?
Here is my draft:

The difficulty of dealing with one's original environment after returning from travel is one of the most common issues face
immigrants. When they get back home, they usually find it difficult to deal with the new developments in their environment. Immigrants who spend long time away from their countries suffer more than those who stay for short time because they get accustomed to the habits and traditions of the new culture and forget their original ones. This phenomenon has different aspects that may increase depending on the differences between the foreign and the original culture. Potential solutions for this problem are realizing the new changes and seeking guidance of relatives.
An important step in overcoming reverse culture shock is realizing the changes happened to the original culture after leaving it. This requires finding the changes on new things they used to see and deal with in the past like people's clothes and restaurants' services. Also, one should be positive about these changes; otherwise, others will feel frustrated and ignore him/her. Further, one needs to realize the negative and positive sides of the new changes in order to understand them well. Moreover, immigrants can make contact with their relatives to inform them of recent changes and teach them how to deal with these changes when they come there. Finally, accepting these changes and understanding them could be an effective way to pass this issue.
Another important step that can help in defeating reverse culture shock is seeking guidance from relatives after and before one go back home. This process should start before returning to the homeland because immigrants need a lot of time to accept all new changes. Besides, one needs to ask them about their experience in dealing with different situations, so he/she is aware of different situations can happen with them. After that, they should ask their relatives to accompany them to different places that may be very important for them. Without relatives' guidance, one may suffer from uncertainty and confusion. Finally, relatives' guidance must be taken seriously.
In conclusion, reverse culture shock is one of the most annoying problems face immigrants, that can cause a lot of confusion and stress. In order to control this issue, one should keep in contact with his/her relatives in order to inform them of new changes happened after he/she traveled. Another important step is to accept the new changes and to be positive with them; otherwise, others will feel frustrated and may stand against him/her. Furthermore, one shouldn't stay long time away from his/her homeland in order to not find a lot of differences between the foreign and the original country. All in all, reverse culture shock could cause a lot of symptoms on immigrants that should be cured by understanding the new changes and asking for relatives' help.
