OddOneOut, welcome! Being only 17 and having to deal with all of this sucks. No wonder you've been suffering from depression and panic attacks. Remember that it wasn't the shower that caused the panic attack. You've no doubt showered many times in your life and never had an attack. Remind yourself that panic attacks are not harmful. Float through these attacks and calmly wait them out. It may take practice but you'll get good at it!
As was suggested above, find a therapist you can relate to. This will help tremendously, also. Docs need to be careful when prescribing meds to younger patients as the side effects may be different. Let us know how you're doing!!
