Hi Skye.
Firstly, love your attitude on taking this! Well done!
Secondly, naturally you'd want help with making this problem not be a problem with you. Its great your mum is supportive. Maybe asking her to take you to a therapist to get a formal assessment is a good idea. Medication and other strategies will definitely help!
Also, since you mentioned you'd like a few people to help cheer you up, talk to your partner and friend. I'm sure they will be more than willing to help. Maybe set up a code word, or phrase that will let them know you need help.
I think meditation may help. It may just help you cope with stressful scenarios.
This and
this are some resources you can look into. Also the app store/play store have heaps and heaps of free apps you can use.
Hope this helps a bit. You're welcome to
PM me anytime you like.
Best of luck! And keep your head up mate, like you're already doing.
