Feeling really depressed - afraid I have MS

I’m just feeling really depressed could use someone to talk too. I’ve been really stressed lately. I am not diagnosed with MS. But I’m feeling afraid with the symptoms I have been experiencing. I feel lost and alone. I’ve had some of these problem over the years but I choose to ignore them but I don’t feel like I can anymore. I have rheumatoid arthritis and I’ve been feeling ill lately.
