Social anxiety problems :/

I have the worst social anxiety. Its bad enough that I go through seasonal depression, that im starting my ocd rituals again, and to top it off just anxiety in general. Its so bad that I can be at home and my husband and I plan to go out and I can think of just checking out somewhere in a store and get sick or someone who's actually being nice and polite thinks im weird because I either dont say anything to anyone or if I do talk to someone I end up mixing my words around and becoming a huge stuttering rambling mess and wonder why I even bothered going to the store or just going out in general :/ its hard because im like I want friends and I want to have people to talk to, but at the same time im scared of the interaction :/
