Gaining weight, does seem to happen to most people on meds. This is because meds slow down the metabolism consequently putting on weight. The only remedy for this is reducing carb take to below 1800 every day. Combined with moderate exercise.
Video games are a good distraction from depression. If math is boring. Is there any other subject you would like to study instead?
I certainly have felt that way about talking to people. But you can always talk about their favorite subject, which is in fact themselves. Asking them where they're from, what they are interested in what they're doing with their lives and so forth.
There is Nami, which is the American organization for the mentally ill and they do run peer to peer support groups and connection groups in some areas. You can Google them and get in touch with their headquarters to see if they provide any of this in your area. Then you will be interacting with people with depression as well. Which would make things a lot easier.
But I have found this I got more of a grip on depression and anxiety. This problem of being worried about what to say to people has disappeared to a great extent, though. On days when things are difficult it can resurface. Take care. I hope and pray everything gets much better for you soon. God bless and best wishes from your friend Francis
