Anxiety

I have been struggleing with anxiety for a while now. At least 2 years. I think I get past it then BAM it rears it ugly head again and I have to fight within myself. I hate it. I dont know if there is something I can do about it or not. It makes me wonder how am I suppose to help others when I cant seem to help myself. I deal with people on a daily basis now that have similar problems to mine, except they have a diagnosis and mental illness to call it and I just sit here and feel crazy, cause Im suppose to be "normal". I dont feel mentally healthy some days. I know Im not struggleing like some, and I am able to have a "normal" life, but most the time I feel like Im faking it. I am trying my hardest to make sure what everyone sees is me being what Im suppose to be. But when no one is looking I let my facade down and let the real feeling out. I know I need therapy, I know I need someone to talk to, but I just dont want to let anyone down. I dont want to let anyone know I feel this way.
