I'm so glad that you are feeling better.

I don't think that people are going to ask you why you have had these changes, I think that instead they are going to be happy to have you along. I went through a similar thing in college and it is a hard adjustment to make. When I went through this process I was awkward and uncomfortable. I didn't really know where I fit in to groups that had already formed. A couple of suggestions for you, (that I wish I had know). 1. Start asking people to do things with you. I had found that people had stopped asking me to do things because they were used to me always saying no. So speak up that you want to be involved in activities. 2. If you are closer to one person (or feel more comfortable), ask them if they will make sure that you know about events that are being planned, this way you are not left out (not intentionally, but because people aren't used to you being there). 3. As for your school work, make sure you balance it with social and extracurricular activities. Don't become a library mouse. 4. For activities that you want to get involved with, don't worry that it is your third year. A lot of people in college switch activities and so you wont be the only new person. If you are interested in activities that your acquaintances are interested in see if they would be willing to go to a group get together with you. Then you will have someone you know there (if it is something they usually go to all the better). The last thing about activities is that often at the beginning of the year they have group meetings where they know that there are going to be new people, no matter the size of the group they are going to want help. Volunteer as a way to get yourself meeting new people and involved in a group.

On a slightly different note, my last suggestion (that hopefully you wont need) is that if you feel the depression is coming back try and catch it early. If you know what signs are that it is coming back keep a watch out for them. (for me it is unexplained tiredness and getting agitated at things that usually wouldn't bother me.) It is easier to try and catch it earlier than it is to run after it when it is way ahead of you. Especially while your in school as you know.

I hope that the transition back to university is a smooth one for you. I hope the advice helps. Feel free to PM me if you have any other questions. I'm back in school this year myself and so am trying to put my advice to you into practice. Good Luck!
