I have depression and taking amphetamines (speed, adderall, vyvanse, (lisdexamfetamine) meth, etc)?

Wow- that is: Quite a mix of drugs- quite worrisome. Please seek the help of an addiction medicine specialist ; /or a psychiatrist asap.

Can cause depression: These drugs, if misused, can all cause depression. A psychiatrist may help you understand whether the depression came first (and you're taking the drugs in an attempt to self-medicate), or if the depression is the side-effect of the drug. There are better ways to help depression than stimulants.
