I need a research topic

There seems to be a lot out there on the topic you are interested in.

For example-

I think it is fine to get ideas and bounce off ideas on peers, including online. But definitely discuss the study with your academic advisors as they will be more familiar with actual research methods, what is feasible and what would fall in the scope of such a project. Even if it is formally allowed, I personally would refrain from using members of an internet forum though, especially one like this where people tend to have strong agendas and you may also be biased based on your extensive prior interactions with the members.

One thing about undergrad research that can be very good to keep in mind is to make it focused and relatively simple, also feasible to complete within the short period of time allocated for it (so you can actually present some conclusions). Specificity was mentioned above, I would add to study a phenomenon that is relatively straightforward and not too mysterious/complex. If the study subject population is given and it's not that you assemble it based on your research question, I would probably look for questions that are especially relevant to this population. Something like how do students cope with academic stress already, where are the specific areas they struggle and could use more external help (including counseling/therapy), what keeps them from utilizing that help? If it is a diverse undergrad population, asking how these patterns and perceptions relate to their specific field of study (major) could also be informative. I don't think it is an issue for an undergrad project if there are already studies addressing similar things - it can actually be an advantage because you can compare and discuss results. Researchers also often conduct similar kinds of studies on different populations to ask how the characteristics of that population affect the outcome. Also, if you want to study perceptions regarding mental health treatments but the majority of the subjects never had any, they are unlikely to have sophisticated perceptions and opinions - another reason to keep it simple and focused.

I'm not sure if it has been mentioned that adjustment disorder is a frequent diagnosis of people away from home for the first time, and due to its nature, it goes away on its own.

Since a lot of psychotherapy research is done on this population, I believe findings are poorly extrapolated. So I hope you are aware of the nature of adjustment disorder and how it can impact this type of research.

I forgot to mention earlier that since there is so much out there on these subjects, maybe you can find an unanswered question or address an pattern of unknown origin to add a slant to it to make it more interesting. My note about a lot out there already wasn't to discourage you from looking into the topic, so that should not be inferred from my previous post.
