Worried I'm going to attack someone or be annoying

I'm on medication that slows me down too much to drive a car. It forces me to ride a bus.
When sitting down, I fear I'm going to tap the person in front on the shoulder and speak
psychotic gibberish. Or be racist. Or laugh in a horrid way. Or smile in a disturbing manner.

Sometimes I fear I'm going to touch men sexually and I'm not gay in anyway. Or attack men violently.
Sometimes I fear pressing the bell too early and annoying the bus driver. I've carried this out before
and s/he was pretty disgruntled.

Sometimes I tic with my hands in a 10 fingered shape circle and spit and make a wobbly high-pitched noise that echoes.
I know this website isn't for Tourette's but I've seen medication discussed on it for this illness.
I'm on Risperdal and this medication controls the tics superbly so the above tics rarely happen,
its usually tics about soccer players and mimicking sports commentators.

I forgot to ask, does anyone have simillar experiences and/or been through the therapy for these OCD symptoms? Or are the pure obsessional/repetitive subtypes (worried about assault/pressing the bell) too difficult to treat?
All I feel when nearly pressing the bell too early is uncomfortableness. I don't think of a pending disaster.
